🟡 Recommended Improvements

Filename	Severity	Violation Description
Test2/P32_Mutithreading_Server.py		The server socket is hardcoded to bind to '127.0.0.1', which will prevent external connections and cause issues in containerized or cloud environments.
Test2/P32_Mutithreading_Server.py		The server port is hardcoded to 1233, which can cause deployment conflicts and makes configuration difficult.
Test2/P32_Multithreading_Client.py		The client is hardcoded to connect to '127.0.0.1', which prevents it from connecting to a server in a different environment without code changes.
Test2/P32_Multithreading_Client.py		The client port is hardcoded to 1233, which can cause connection issues if the server port is changed.
Test2/P38_HashingFile.py		The script uses a hardcoded absolute file path, which will fail in any other environment or on any other user's machine.
Test2/P38_HashingFile.py		The script uses the MD5 hashing algorithm, which is known to be insecure and vulnerable to collisions.

🎯 Conclusion

• Externalize all environment-specific configurations, such as IP addresses, ports, and file paths, using environment variables or command-line arguments. This is critical for creating portable and deployable applications.
• Avoid using outdated and insecure cryptographic algorithms like MD5. Standardize on modern, secure alternatives such as SHA-256 for any hashing needs.

Important

Please carefully assess each DevOps and migration violation's impact before proceeding to ensure smooth transitions between environments.

Hardcoded IP Address for Server Binding

I noticed the server is hardcoded to bind to 127.0.0.1. This restricts connections to the local machine only and will prevent the service from being accessible in containerized environments (like Docker) or when deployed to a cloud VM.

Let's change this to 0.0.0.0 to allow the server to listen on all available network interfaces. This makes the application portable and ready for deployment.

Suggested change

	host = '127.0.0.1'
	host = '0.0.0.0'

[appmod-pr-genie]

Hardcoded Port Number

I see the port number 1233 is hardcoded. This can lead to port conflicts in different environments and makes it difficult to reconfigure the application without changing the code.

Let's externalize this by reading the port from an environment variable, with a fallback to a default value. This is a standard practice for building configurable and portable applications.

Suggested change

	port = 1233
	port = int(os.getenv('PORT', 1233))

[appmod-pr-genie]

Hardcoded IP Address for Client Connection

I noticed the client is hardcoded to connect to 127.0.0.1. This will only work for local testing and will fail when the client and server are deployed on different machines or in different containers.

Let's make this configurable by reading the target host from an environment variable. This will allow you to point the client to any server (e.g., a staging or production endpoint) without modifying the code.

Suggested change

	host = '127.0.0.1'
	host = os.getenv('SERVER_HOST', '127.0.0.1')

[appmod-pr-genie]

Hardcoded Port Number in Client

I see the client is configured to connect to port 1233, which is hardcoded. This creates a tight coupling with the server's configuration and requires code changes if the server port is ever updated.

Let's externalize this by reading the port from an environment variable, ensuring it stays in sync with the server's configuration.

Suggested change

	port = 1233
	port = int(os.getenv('SERVER_PORT', 1233))

[appmod-pr-genie]

Hardcoded File Path

I've spotted a hardcoded absolute file path here. This path is specific to one user's machine and will cause the script to fail when run in any other environment, such as a CI/CD pipeline, a Docker container, or another developer's machine.

Let's make this script portable by accepting the file path as a command-line argument. This is a much more flexible and robust approach.

[appmod-pr-genie]

Use of Insecure MD5 Hashing Algorithm

I noticed the script is using hashlib.md5(). The MD5 algorithm is considered cryptographically broken and is not suitable for security-sensitive applications due to its vulnerability to hash collisions.

Let's switch to a more secure hashing algorithm like SHA-256. This will provide much stronger guarantees for file integrity checks.

Suggested change

	hasher = hashlib.md5()
	hasher = hashlib.sha256()

🔍 Technical Quality Assessment

📋 Summary

This update adds a collection of tools for data organization, security, and basic calculations. While these tools provide new capabilities for handling information, several critical errors were found that could cause the system to crash or produce incorrect results for our users. These issues must be addressed to ensure a reliable and professional experience.

💼 Business Impact

• What Changed: We have introduced new ways for the system to sort information, store data efficiently, and communicate between different parts of the software. We also added a simple game and a tool to protect text using a secret code.
• Why It Matters: These tools are the building blocks for faster and more organized software. However, because many of these new tools have 'bugs' (errors), using them right now could lead to lost data, system crashes, or incorrect calculations that might frustrate users or lead to wrong business decisions.
• User Experience: Users will have access to new features like a 'Guess the Number' game and 'Hangman.' However, they might experience crashes if they type in the wrong thing (like a letter instead of a number) or find that the games don't always let them win even when they are right.

🎯 Purpose & Scope

• Primary Purpose: New Feature & Utility Addition

Undefined Variable Reference

I noticed that we're trying to use variables a and b in the addition logic, but they haven't been defined anywhere in the function or global scope. This will cause a NameError as soon as the code reaches this line. We should use the variables first_number and second_number that were collected from the user input earlier.

Suggested change

	print('Addition is:', int(a) + int(b))
	print('Addition is:', int(first_number) + int(second_number))

[appmod-pr-genie]

Infinite Recursion on Negative Input

I noticed that when a negative number is entered, the function prints an error message but continues execution. Since it doesn't return early, it proceeds to the recursive call, leading to a RecursionError (stack overflow). We should return None or raise an exception immediately after detecting a negative input.

Suggested change

	print('Invalid entry! Cannot find factorial of a negative number')
	return None

[appmod-pr-genie]

^{JAS - Just a suggestion}
Residual Debug Print

It looks like there's a "Hello" print statement left in the base case logic. This appears to be debugging code that might clutter the output for the end user. We should remove it to keep the function's output clean and focused on the result.

[appmod-pr-genie]

Redundant Empty Line in Pattern 5

I noticed that pattern5 prints an extra empty line at the start. This happens because the loop starts at i=0, resulting in range(-1) for stars. We should start the range from 1 to match the intended pattern.

Suggested change

	for i in range(level + 1):
	for i in range(1, level + 1):

[appmod-pr-genie]

Nested Function Definition in Main Block

It looks like pattern6 is defined inside the if __name__ == '__main__': block. This makes the function inaccessible if the module is imported elsewhere. Let's move the definition to the top level with the other functions.

[appmod-pr-genie]

Potential FileExistsError

I notice we're calling os.mkdir('newDir1') without checking if the directory already exists. If this script is run a second time, it will crash with a FileExistsError. We should add a check or use exist_ok=True to make this more robust.

Suggested change

	os.mkdir('newDir1')
	if not os.path.exists('newDir1'):
	os.mkdir('newDir1')

[appmod-pr-genie]

Off-by-One Error in Random Range

I noticed that the random number is generated between 0 and 21, but the user prompt suggests the range is 0 to 20. This means a user could never guess the number 21 if it's generated, leading to a frustrating experience. We should align the generation range with the user instructions.

Suggested change

	randomNumber = random.randint(0, 21)
	randomNumber = random.randint(0, 20)

[appmod-pr-genie]

Potential Runtime Crash on Invalid Input

Currently, if a user enters something that isn't a number (like a letter or a blank space), the program will crash with a ValueError. It's a good practice to wrap the input conversion in a try-except block to handle these cases gracefully and keep the game running.

Suggested change

	number = int(input('Enter the number between 0 to 20: '))
	try:
	number = int(input('Enter the number between 0 to 20: '))
	except ValueError:
	print('Please enter a valid integer.')
	continue

[appmod-pr-genie]

Global State for Iteration Counting

Using a global variable iterations to track search progress makes the function non-thread-safe and prone to errors if called multiple times without manual resets. It's better to return the count alongside the result or encapsulate it within a class to maintain state properly.

Suggested change

	def sequentialSearch(target, List):
	'''This function returns the position of the target if found else returns -1'''
	position = 0
	global iterations
	iterations = 0
	while position < len(List):
	iterations += 1
	if target == List[position]:
	return position
	position += 1
	return -1
	def sequentialSearch(target, List):
	'''This function returns the position and iterations of the target if found else returns -1, iterations'''
	position = 0
	iterations = 0
	while position < len(List):
	iterations += 1
	if target == List[position]:
	return position, iterations
	position += 1
	return -1, iterations

[appmod-pr-genie]

State Management Issue: Global Variable Usage

Using global iterations to track the number of steps is risky. If this function is imported into another module or called in a loop, it relies on a global state that might not be initialized or could be overwritten unexpectedly. It's much safer to return the iteration count along with the result or handle it within a class structure to ensure thread safety and modularity.

Reasons & Gaps

Reasons

1. Global variables create hidden dependencies between functions and the module state.
2. Makes the function difficult to test in isolation or use in multi-threaded environments.
3. Violates encapsulation principles by modifying state outside the function's local scope.

Gaps

1. The current script is a standalone example where global scope side effects are contained.
2. Python's global keyword behavior is deterministic within the module scope.

Performance Optimization: Missing Early Exit

I notice that this implementation of Bubble Sort always runs in O(n²) time, even if the list becomes sorted early. We can optimize this by adding a flag to check if any swaps occurred during a pass. If no swaps happen, the list is already sorted, and we can exit early. This improves the best-case time complexity to O(n).

Suggested change

	def bubbleSort(List):
	for i in range(len(List)):
	for j in range(len(List) - 1, i, -1):
	if List[j] < List[j - 1]:
	List[j], List[j - 1] = List[j - 1], List[j]
	return List
	def bubbleSort(List):
	for i in range(len(List)):
	swapped = False
	for j in range(len(List) - 1, i, -1):
	if List[j] < List[j - 1]:
	List[j], List[j - 1] = List[j - 1], List[j]
	swapped = True
	if not swapped:
	break
	return List

[appmod-pr-genie]

Logical Error in Insertion Sort Implementation

I notice a potential logic issue in how the currentNumber is handled. In the if block, we are swapping elements, but in the else block, we explicitly assign currentNumber to List[j + 1]. If the if condition is met and a swap occurs, the value originally in currentNumber is moved, but the variable currentNumber itself isn't updated. This mix of swapping and explicit assignment can lead to incorrect values being placed in the list if the logic isn't consistent. A cleaner approach for Insertion Sort is to shift elements and then place the currentNumber once.

Suggested change

	for j in range(i - 1, -1, -1):
	if List[j] > currentNumber :
	List[j], List[j + 1] = List[j + 1], List[j]
	else:
	List[j + 1] = currentNumber
	break
	j = i - 1
	while j >= 0 and List[j] > currentNumber:
	List[j + 1] = List[j]
	j -= 1
	List[j + 1] = currentNumber

Reasons & Gaps

Reasons

1. Standard insertion sort logic involves shifting elements rather than multiple swaps for efficiency.
2. Mixing swaps with explicit assignments of a cached variable can lead to data duplication or loss.
3. The current loop structure makes it difficult to ensure the 'currentNumber' is always placed correctly.

Gaps

1. The current implementation might work for some inputs due to the swap, but it is non-standard and prone to errors.
2. The interaction between the swap at line 16 and the assignment at line 18 is logically fragile.

[appmod-pr-genie]

Performance Issue: Inefficient List Removal

Using list.remove(a[0]) inside a loop results in O(n) complexity for each removal because Python must shift all subsequent elements. In a merge operation, this turns an O(n) process into O(n²). We should use index tracking or pop(0) (though pop(0) is also O(n)) to maintain the expected O(n log n) performance of Merge Sort.

Suggested change

	if a[0] < b[0]:
	c.append(a[0])
	a.remove(a[0])
	else:
	c.append(b[0])
	b.remove(b[0])
	if a[i] < b[j]:
	c.append(a[i])
	i += 1
	else:
	c.append(b[j])
	j += 1

[appmod-pr-genie]

Logic Error in Partitioning

I noticed a small logic error in the partition function. When swapping the pivot into its final position, we're using myList[right]. However, based on the loop conditions, right is the correct index where the pivot should land, but the code currently swaps myList[start] with myList[right]. While this looks correct, the inner loop for right (line 31) uses >= pivot, which can lead to right stopping at an index that doesn't correctly represent the split point if not handled carefully. More importantly, the quickSort call on line 59 passes the original list which is then modified in-place, but the quicksortBetter call on line 63 uses the same list which has already been sorted, making the second benchmark invalid.

Suggested change

	List = [3, 4, 2, 6, 5, 7, 1, 9]
	start = time.time()
	print('Sorted List:',quickSort(List, 0, len(List) - 1))
	stop = time.time()
	print('Time Required:', (stop - start))
	start = time.time()
	print('Sorted List:', quicksortBetter(List))
	List = [3, 4, 2, 6, 5, 7, 1, 9]
	start = time.time()
	print('Sorted List:', quickSort(List[:], 0, len(List) - 1))
	stop = time.time()
	print('Time Required:', (stop - start))
	start = time.time()
	print('Sorted List:', quicksortBetter(List[:]))

Reasons & Gaps

Reasons

1. The first sort call modifies the input list in-place because Python lists are mutable
2. The second sort algorithm receives an already sorted list, skewing performance results
3. Using a slice [:] creates a copy, ensuring both algorithms start with the same data

Gaps

1. The partitioning logic itself is a standard Hoare-like partition but the benchmarking logic is flawed due to in-place mutation.
2. The impact on the sort result depends on the specific pivot selection and list distribution.

Misleading Help Message in CLI

I noticed that the error message suggests typing ArgumentParser -h, but the actual script name is P29_ArgumentParser.py. This might confuse users trying to find help. It's better to use %(prog)s or the actual filename to ensure the instructions are accurate.

Suggested change

	print('Dude give some arguments! Type ArgumentParser -h for more details')
	print(f'Dude give some arguments! Type python {parser.prog} -h for more details')

[appmod-pr-genie]

Potential Out of Bounds in insertAfterIndex

When inserting after an index, we calculate index + 1. If the user provides the last valid index of the array, index + 1 will equal self.size, causing an IndexError because list indices are 0-based.

Suggested change

	for i in range(self.myLen(), index + 1, -1):
	self.items[i] = self.items[i - 1]
	self.items[index + 1] = element
	if index + 1 < self.size:
	for i in range(self.myLen(), index + 1, -1):
	if i < self.size:
	self.items[i] = self.items[i - 1]
	self.items[index + 1] = element

[appmod-pr-genie]

Data Integrity Issue in delete Method

The delete method sets an element to None but doesn't shift subsequent elements. This breaks the assumption in insert methods (which use myLen) that elements are contiguous, leading to data being overwritten during future insertions.

Suggested change

	Index = self.items.index(element)
	self.items[Index] = None
	Index = self.items.index(element)
	self.items.pop(Index)
	self.items.append(None)

Reasons & Gaps

Reasons

1. Creating gaps with None breaks the logic of myLen() used in insertion
2. Subsequent insertions will shift elements into these 'None' slots incorrectly
3. Leads to a fragmented array where logical length and physical layout mismatch

Gaps

1. Implementation choice between 'sparse array' vs 'contiguous array' is ambiguous
2. Current insert logic assumes contiguous, but delete creates a sparse structure

Potential AttributeError in remove method

I noticed a potential crash in the remove method. If the item we're looking for isn't in the list, current will eventually become None. When the loop finishes, the code tries to call current.getNext(), which will raise an AttributeError. We should add a check to ensure the item was actually found before attempting to modify the list pointers.

Suggested change

	if previous == None:
	if not found:
	return
	if previous == None:

Potential Resource Leak: Unreachable Socket Closure

I noticed that the ClientSocket.close() call is placed after an infinite while True loop. Since the loop has no break condition, the socket will never be explicitly closed if the program is terminated normally (e.g., via Ctrl+C), which can lead to resource leaks. We should wrap the communication logic in a try-finally block to ensure the socket is always closed.

Suggested change

	while True:
	Input = input('Say Something: ')
	ClientSocket.send(str.encode(Input))
	Response = ClientSocket.recv(1024)
	print(Response.decode('utf-8'))
	ClientSocket.close()
	try:
	while True:
	Input = input('Say Something: ')
	ClientSocket.send(str.encode(Input))
	Response = ClientSocket.recv(1024)
	print(Response.decode('utf-8'))
	finally:
	ClientSocket.close()

[appmod-pr-genie]

Unchecked Socket Reception

We're calling recv(1024) without checking if the server has closed the connection. In TCP, recv returns an empty string/bytes when the peer closes the connection. If the server disconnects, this client will enter an infinite loop of empty prints or crash on decoding. We should check the response length and break the loop if it's empty.

Suggested change

	Response = ClientSocket.recv(1024)
	print(Response.decode('utf-8'))
	Response = ClientSocket.recv(1024)
	if not Response:
	print("Connection closed by server.")
	break
	print(Response.decode('utf-8'))

[appmod-pr-genie]

Potential Runtime Error: Decoding Empty Data

I noticed that we're attempting to decode the data variable before checking if it's empty. If a client disconnects gracefully, recv returns an empty byte string. Attempting to access or process this data before the if not data check can lead to unexpected behavior or errors in more complex logic. It's safer to validate the data first.

Suggested change

	data = connection.recv(2048)
	reply = 'Server Says: ' + data.decode('utf-8')
	if not data:
	data = connection.recv(2048)
	if not data:
	break
	reply = 'Server Says: ' + data.decode('utf-8')

[appmod-pr-genie]

Resource Leak: Missing Exception Handling for Client Closure

We should wrap the client communication in a try...finally block. Currently, if an exception occurs during recv or sendall (like a connection reset), the connection.close() call at line 30 might be skipped. This would leave the socket open, leading to a resource leak over time as more clients connect.

Suggested change

	def threaded_client(connection):
	connection.send(str.encode('Welcome to the Server\n'))
	while True:
	data = connection.recv(2048)
	reply = 'Server Says: ' + data.decode('utf-8')
	if not data:
	break
	connection.sendall(str.encode(reply))
	connection.close()
	def threaded_client(connection):

	while True:
	data = connection.recv(2048)
	if not data:

Unreachable Code: Server Socket Close

I see that ServerSocket.close() is placed after an infinite while True loop. This means the server socket will never actually be closed gracefully by this script, as the loop never terminates. If we intend to shut down the server, we should handle a KeyboardInterrupt to ensure the port is released properly.

Suggested change

	while True:
	Client, address = ServerSocket.accept()
	print('Connected to: ' + address[0] + ':' + str(address[1]))

Potential Crash in insertLast on Empty List

I noticed that insertLast assumes the list already has at least one node. If we call this on an empty list, current will be None, and current.getNext() will throw an AttributeError. We should handle the empty list case by calling insertFirst or setting the head directly.

Suggested change

	current = self.head
	if self.head is None:
	self.insertFirst(data)
	return
	current = self.head

Broken Doubly Linked List Pointers in remove()

In a doubly linked list, when we remove a node, we need to update both the next pointer of the previous node and the previous pointer of the next node. Currently, we're only updating the next pointer, which breaks the integrity of the bidirectional links.

Suggested change

	if previous == None:
	self.head = current.getNext()
	else:
	previous.setNext(current.getNext())
	if previous == None:
	self.head = current.getNext()

Incorrect Range Check

We're checking if the key is greater than myArray[high - 1], but the array actually contains elements up to index high. This means if the user searches for the very last element in the array, the program will incorrectly report it as out of range.

Suggested change

	if(key < myArray[low] or key > myArray[high - 1]):
	if(key < myArray[low] or key > myArray[high]):

Reasons & Gaps

Reasons

1. The condition incorrectly excludes the last element of the array from the search
2. Users searching for the maximum value will receive a false 'out of range' error
3. Logic fails to account for the inclusive upper bound of the generated array

Gaps

1. The array initialization loop goes up to ARRAY_SIZE inclusive
2. high is set to ARRAY_SIZE, making high the last valid index

[appmod-pr-genie]

Inefficient Array Insertion

Using insert(i, i) inside a loop to build a large array is quite slow because it can trigger memory reallocations and shifts. Since we're just building a list of sequential numbers, using list(range(...)) or append() is much more efficient and idiomatic.

Suggested change

	myArray = []
	for i in range(0, ARRAY_SIZE + 1):
	myArray.insert(i, i)
	myArray = list(range(ARRAY_SIZE + 1))

[appmod-pr-genie]

Potential NameError: Undefined Thread Variables

I noticed that Thread1 and Thread2 are defined inside conditional blocks within a loop. If the random logic only triggers one branch (e.g., only Readers are created), the call to .join() for the other variable will crash the program with a NameError. We should track all created threads in a list and join them systematically.

Suggested change

	for i in range(0, 10):
	randomNumber = random.randint(0, 100) #Generate a Random number between 0 to 100
	if(randomNumber > 50):
	Thread1 = thread.Thread(target = Reader)
	Thread1.start()
	else:
	Thread2 = thread.Thread(target = Writer)
	Thread2.start()
	Thread1.join()
	Thread2.join()
	threads = []
	for i in range(0, 10):
	randomNumber = random.randint(0, 100)
	if(randomNumber > 50):
	t = thread.Thread(target = Reader)
	else:
	t = thread.Thread(target = Writer)
	t.start()
	threads.append(t)
	for t in threads:
	t.join()

Suboptimal Concurrency: Reader Starvation/Blocking

In this implementation, you're using a single Mutex (Lock) for both readers and writers. This effectively turns the 'Reader-Writer' problem into a 'Single-User' problem where only one person can read at a time. Usually, we want multiple readers to be able to read simultaneously while only blocking for writers. Consider using a Semaphore or a specific Reader-Writer lock pattern if performance is a concern.

Reasons & Gaps

Reasons

1. Mutex on readers prevents concurrent read access, which is the primary goal of RW patterns
2. Serializing reads significantly degrades performance in read-heavy workloads
3. Does not follow the standard solution for the First or Second Reader-Writer problem

Gaps

1. The script is a 'simple' example where strict mutex might be the intended educational goal
2. Implementation of a full RWLock requires significantly more boilerplate code

[appmod-pr-genie]

Incorrect Win Condition Logic

I noticed a logic error in how we check if the user has won. Using Counter(letterGuessed) == Counter(word) will fail if the user guesses letters in a different order or if the word has duplicate letters that weren't guessed multiple times. We should check if all unique characters in the word are present in the set of guessed letters instead.

Suggested change

	if (Counter(letterGuessed) == Counter(word)):
	if all(char in letterGuessed for char in word):

[appmod-pr-genie]

Incorrect Correct Guess Counter

I see we're incrementing the correct variable inside the loop that prints the word. This will cause the counter to increase every time the word is displayed, regardless of whether the guess was new or correct. Since correct isn't actually used to determine the win state, and the logic is flawed, we should remove this increment or fix the tracking logic.

Suggested change

	correct += 1
	print(char, end = ' ')

[appmod-pr-genie]

Case Sensitivity Issue in Guesses

I noticed that the game doesn't normalize the input case. If the secret word is 'Apple' and the user guesses 'a', it might not match. To make the game more user-friendly and functionally robust, we should convert both the word and the guess to lowercase.

Suggested change

	guess = str(input('Enter a letter to guess: '))
	guess = str(input('Enter a letter to guess: ')).lower()

Reasons & Gaps

Reasons

1. Python string comparison is case-sensitive by default ('A' != 'a')
2. Users may provide uppercase input which would result in a false negative guess
3. Ensures consistency between user input and the internal word list

Gaps

1. The word list provided is all lowercase, but external word lists might vary
2. Input normalization is a standard practice for character-based games

Security Risk: Use of Weak Hashing Algorithm (MD5)

I notice we're using MD5 to calculate the file hash. While MD5 is fast, it's considered cryptographically broken because it's vulnerable to collision attacks. If this is used for security-critical integrity checks, an attacker could potentially provide a malicious file with the same hash. We should consider using a more secure algorithm like SHA-256 for better protection.

Suggested change

	hasher = hashlib.md5()
	hasher = hashlib.sha256()

[appmod-pr-genie]

Incorrect Wrap-around Logic in Encryption

I noticed a logic error in how the alphabet wrap-around is handled. Using num % 25 and then subtracting 1 will result in incorrect character mapping (e.g., 'z' might not map back to 'a' correctly). We should use the modulo operator on the full alphabet length (26) to ensure a proper circular shift.

Suggested change

	num += key
	if num>25:
	num=num%25
	num=num-1
	num = (num + key) % 26

[appmod-pr-genie]

Redundant and Flawed Boundary Check in Decryption

The check if num > 25 inside the decryption function is logically misplaced because LETTERS.find() returns an index between 0-25. Furthermore, the subtraction logic for decryption should handle negative results using modulo 26 to ensure it wraps correctly to the end of the alphabet.

Suggested change

	if num>25:
	num=num%25
	num=num-1
	num = num -key
	num = (num - key) % 26

[appmod-pr-genie]

Incorrect Character Wrapping Logic

I notice a small logic error in how we handle character wrapping when the index exceeds the alphabet length. Using num % 25 and then subtracting 1 will result in incorrect character mapping (e.g., 'z' with key 1 might not wrap to 'a' correctly). We should use the modulo operator with the full length of the alphabet (26) to ensure a clean wrap-around.

Suggested change

	num += key
	if num>25:
	num=num%25
	num=num-1
	num = (num + key) % 26

[appmod-pr-genie]

Broken Decryption Logic for Large Keys

I see a potential issue in the decryption function. We're checking if num > 25 before subtracting the key, but find() always returns an index between 0-25. This means the wrapping logic never triggers during decryption, and subtracting the key will result in negative indices. While Python handles negative indices, it won't wrap correctly for keys larger than the character's position. We should use modulo 26 here as well.

Suggested change

	if num>25:
	num=num%25
	num=num-1
	num = num -key
	num = (num - key) % 26

Performance Issue: Sequential Port Scanning

Scanning ports sequentially from 1 to 1024 using a single thread is extremely slow, especially if the network has high latency or if many ports are filtered. Each connect_ex call waits for a timeout. We should consider using a timeout on the socket to speed up the process or implement multi-threading for concurrent scanning.

Suggested change

	s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
	connection = s.connect_ex((host, port)) #NOTE: connect() needs a tuple!
	s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
	s.settimeout(0.1)
	connection = s.connect_ex((host, port))

Logic Error: Incomplete Port Range

I notice we're scanning the range (1, 1024), which in Python's range function actually stops at 1023. If the intent was to scan all well-known ports up to and including 1024, we should adjust the range to (1, 1025).

Suggested change

	for port in range(1, 1024):
	for port in range(1, 1025):

Potential Deadlock in Pipe Communication

I notice we're calling child.recv() in the main process, but the child end of the pipe was passed to process2. In a multiprocessing.Pipe(), only the end that didn't send the data should be receiving it. Since process2 (childData) is using the child connection to send data, the main process should use the parent connection to receive it. Attempting to receive from the same end that is being used by another process to send (or that has been closed) will cause the program to hang indefinitely.

Suggested change

	print(parent.recv()) # Display data received from child (BYE)
	print(child.recv()) # Display data received from parent (HELLO)
	print(parent.recv()) # Display data received from child (BYE)
	print(parent.recv()) # Display data received from parent (HELLO)

Misleading or Vague Function Name

The function name 'justPrint' uses camelCase, which violates Python's snake_case convention. Additionally, the name is vague and doesn't reflect that the function also performs arithmetic and user input operations.

Suggested change

	def justPrint(text):
	def print_and_calculate_values(text):

Reasons & Gaps

Reasons

1. Python naming conventions (PEP 8) require function names to be in snake_case
2. The name 'justPrint' is misleading as the function body contains complex logic beyond printing
3. Descriptive names like 'print_and_calculate_values' improve code maintainability

Gaps

1. The function's primary intent seems to be a demonstration script rather than a production utility
2. 'justPrint' might be a legacy name from a developer transitioning from Java/JS

The parameter name 'number' is explicitly listed as a forbidden generic name. Using a more descriptive name like 'input_value' or 'n' (if following mathematical conventions) is preferred.

Suggested change

Reasons & Gaps

Reasons

1. The name 'number' is explicitly identified as a forbidden generic name in the coding standard
2. Generic names reduce semantic clarity regarding the specific type or role of the input
3. Using 'n' aligns with standard mathematical notation for factorial operations

Gaps

1. In mathematical contexts, 'number' is often considered a descriptive domain term despite being on the forbidden list
2. The function name 'factorial' provides significant context that may mitigate the generic nature of the parameter

	user_input = int(input('Enter the Number to find the factorial of: '))

Reasons & Gaps

Reasons

1. Python's PEP 8 style guide mandates the use of snake_case for variable and function names
2. Consistent casing improves code maintainability and follows community-wide expectations
3. Mixed casing styles within a Python project can lead to confusion and reduced readability

Reasons & Gaps

Reasons

1. Python naming conventions (PEP 8) recommend snake_case for variable names
2. Consistent casing across the codebase reduces cognitive load for developers
3. Improves alignment with standard Python library naming patterns

	def is_prime(number):

Reasons & Gaps

Reasons

1. Function names returning booleans should start with is, has, or can
2. Improves code predictability by signaling the expected return type
3. Follows Python PEP 8 naming conventions for boolean-like functions

Gaps

1. The function currently prints results instead of just returning a boolean

	is_prime = False

Reasons & Gaps

Reasons

1. PEP 8 recommends snake_case for all variable and function names
2. Consistent casing reduces cognitive load when reading Python code
3. Avoids mixing naming styles within a single Python module

	for directory_index in range(1, 10):

Reasons & Gaps

Reasons

1. Descriptive names clarify the purpose of the loop variable within the logic
2. Improves maintainability when the loop body involves complex string manipulations
3. Helps distinguish between multiple nested loops if the script expands in the future

Reasons & Gaps

Reasons

1. Python's PEP 8 style guide explicitly recommends snake_case for variable names
2. Consistent casing improves code maintainability and follows community standards

Vague Verb in Function Name

The function name guess consists of a single generic verb. Adding a noun, such as play_guessing_game, makes the function's purpose clearer.

Reasons & Gaps

Reasons

1. Generic verbs without nouns fail to describe the specific action target
2. 'play_guessing_game' explicitly communicates the function's role in the application
3. Descriptive names act as internal documentation for future code maintenance

Gaps

1. In a small script, a short name like 'guess' might be considered contextually sufficient
2. The function is the primary logic of the script, making its purpose somewhat obvious

Suggested change

	def sequentialSearch(target, List):
	def sequentialSearch(target, items):

Reasons & Gaps

Reasons

1. Using 'List' as a variable name shadows the built-in Python list type
2. Hungarian notation (type prefixes) is discouraged in modern Python development
3. Descriptive names like 'items' improve clarity regarding the variable's purpose

Gaps

1. 'List' is a built-in type in Python, making its use as a variable name technically valid but highly discouraged

2. Reduces cognitive load by using full words instead of clipped abbreviations
3. Improves maintainability by providing better context for the variable's role

Gaps

1. 'ans' is widely understood in mathematical or algorithmic contexts
2. The scope of the variable is very small, reducing the impact of the abbreviation

Function Naming Convention Violation

The function name 'binarySearch' uses camelCase, which violates the Python snake_case convention. Additionally, 'List' as a parameter name is a built-in type name and should be more descriptive.

Suggested change

	def binarySearch(target, List):
	def binary_search(target, sorted_list):

Reasons & Gaps

Reasons

1. Python naming conventions (PEP 8) require function names to be in snake_case
2. Using 'List' as a parameter name shadows the built-in list type and lacks context
3. 'binary_search' and 'sorted_list' provide better clarity and follow language standards

Gaps

1. The function name is technically descriptive of the algorithm being used
2. camelCase is common in other languages and might be a personal preference of the developer

Cryptic Abbreviation in Variable Name

The variable name 'ans' is a cryptic abbreviation for 'answer' or 'result'. Using a more descriptive name like 'result_index' or 'target_position' improves code clarity.

Suggested change

	ans = binarySearch(target, List)
	result_index = binary_search(target, sorted_list)

Reasons & Gaps

Reasons

1. Cryptic abbreviations increase cognitive load when reading logic flow
2. 'result_index' explicitly describes what the value represents (the index of the target)
3. Avoids non-standard abbreviations as per enterprise maintainability standards

Gaps

1. 'ans' is a very common abbreviation in competitive programming or mathematical scripts
2. The local scope of the variable makes its purpose relatively easy to infer

Vague Generic Variable Name

The variable name 'List' is too generic and shadows the built-in Python type. A more descriptive name like 'unsorted_numbers' or 'sample_data' would be more expressive.

Suggested change

	List = [3, 4, 2, 6, 5, 7, 1, 9]
	unsorted_numbers = [3, 4, 2, 6, 5, 7, 1, 9]

Reasons & Gaps

Reasons

1. 'List' is a functional generic name that lacks semantic meaning about the data
2. Shadowing built-in types is a poor practice that can cause confusion in larger scopes
3. Expressive names like 'unsorted_numbers' clarify the intent of the test data

Gaps

1. In a small script, the variable's purpose is immediately obvious from the assignment
2. Shadowing 'List' is a technical concern but doesn't break this specific logic

Violates Language-Specific Case Convention

In Python, function names should follow the snake_case convention. The current name insertionSort uses camelCase, which is more common in Java or JavaScript.

Suggested change

	def insertionSort(List):
	def insertion_sort(List):

Reasons & Gaps

Reasons

1. PEP 8 recommends using lowercase words separated by underscores for function names
2. Consistent naming conventions improve code maintainability and readability for Python developers
3. Adhering to language-specific standards reduces cognitive load during code reviews

Gaps

1. The project might be following a legacy naming convention that overrides PEP 8 standards
2. The developer might be transitioning from a camelCase-dominant language like Java

Forbidden Generic Name

The variable name 'List' is a forbidden generic name and also conflicts with the built-in type list in Python. Using descriptive names like numbers or elements is recommended.

Suggested change

	def insertionSort(List):
	def insertionSort(items):

Reasons & Gaps

Reasons

1. 'List' is a generic term that doesn't describe the contents of the collection
2. Shadowing or mimicking built-in type names can lead to confusion and potential bugs
3. Descriptive names like 'items' or 'collection' provide better context for the data

Single-Character Parameter Names

The parameters 'a' and 'b' are single-character names which are non-descriptive. Using more expressive names like 'left_half' and 'right_half' improves code readability and maintainability.

Suggested change

	def merge(a,b):
	def merge(left_half, right_half):

Reasons & Gaps

Reasons

1. Single-character names fail to convey the purpose or type of data being handled
2. Descriptive names reduce cognitive load when reading complex algorithmic logic
3. Standard naming conventions prefer full words over single letters for parameters

Gaps

1. Single-letter variables are common in mathematical or algorithmic implementations
2. The context of a merge sort algorithm makes the purpose of these variables relatively clear

[appmod-pr-genie]

^{JAS - Just a suggestion}
Single-Character Variable Name

The variable 'c' is a single-character name. A more descriptive name like 'merged_list' or 'result' would better indicate that this list stores the combined elements.

Suggested change

	c = []
	merged_list = []

Reasons & Gaps

Reasons

1. Variable 'c' provides no semantic meaning regarding its role in the merge process
2. Meaningful names help developers understand the state of the algorithm at a glance
3. Using 'merged_list' explicitly defines the variable's intent as the output container

Gaps

1. In short algorithmic functions, single letters are sometimes used for temporary storage
2. The scope of the variable is very limited within the merge function

Incorrect Case Convention (camelCase in Python)

Python function names should follow the snake_case convention. Additionally, the parameter 'x' is non-descriptive; consider using 'input_list'.

Suggested change

Reasons & Gaps

Reasons

1. PEP 8 explicitly recommends snake_case for function names in Python
2. Consistency with language standards is vital for shared codebase maintainability
3. 'input_list' is more descriptive than the generic single-letter parameter 'x'

Gaps

	List = [3, 4, 2, 6, 5, 7, 1, 9]
	unsorted_numbers = [3, 4, 2, 6, 5, 7, 1, 9]

Reasons & Gaps

Reasons

1. Variable names should be lowercase in Python to distinguish them from classes
2. 'List' is a generic type name and does not describe the content of the data
3. 'unsorted_numbers' provides clear context for what the data represents in the script

Gaps

1. The variable is used in a simple main block where context is immediate
2. Capitalization avoids direct collision with the 'list' keyword but violates style

Variable Naming Violation

The parameter name 'myList' uses camelCase and contains a type suffix ('List'). In Python, 'snake_case' is the standard convention, and names should avoid type indicators.

Suggested change

	def quickSort(myList, start, end):
	def quickSort(items, start, end):

Reasons & Gaps

Reasons

1. Python naming conventions (PEP 8) require snake_case for variables and parameters
2. Including 'List' in the name is redundant and follows Hungarian notation patterns
3. 'items' or 'elements' provides better abstraction than referencing the data structure

Gaps

1. 'myList' is partially descriptive but violates Python's PEP 8 naming conventions
2. The term 'List' is a type indicator which is discouraged by the standard

Function Naming Convention

The function name 'quickSort' uses camelCase, which violates the Python snake_case convention. It should be renamed to 'quick_sort' for consistency with language standards.

Suggested change

	def quickSort(myList, start, end):
	def quick_sort(myList, start, end):

Reasons & Gaps

Reasons

1. PEP 8 style guide specifies that function names should be lowercase with underscores
2. Consistent casing improves readability and maintainability for Python developers
3. 'quick_sort' aligns with standard Python library naming patterns

Gaps

1. The name is descriptive of the algorithm but violates language-specific casing rules

Vague Variable Name

The variable name 'temp' is generic. While common in swap operations, using a more descriptive name like 'temporary_element' or using Pythonic tuple unpacking is preferred.

Suggested change

	temp=myList[left]
	myList[left], myList[right] = myList[right], myList[left]

Reasons & Gaps

Reasons

1. Generic names like 'temp' provide low semantic value to the code logic
2. Python supports atomic swapping which eliminates the need for temporary storage
3. Reducing intermediate variables simplifies the function's cognitive load

Gaps

1. 'temp' is a standard idiom for swaps, making it a borderline violation
2. Python's tuple unpacking makes the 'temp' variable entirely unnecessary

Vague Variable Name

The variable name arg is a common abbreviation. Expanding it to args or arguments improves clarity, especially when multiple argument sets might exist.

Suggested change

	arg = parser.parse_args()

Reasons & Gaps

Reasons

1. Fully expressive names like 'args' or 'arguments' are preferred over shortened versions
2. Standardizing on 'args' aligns with common documentation examples for the argparse library
3. Reduces ambiguity if the script grows to include more complex logic

Gaps

1. 'arg' is a very common abbreviation in CLI scripts and is often considered acceptable in short functions
2. The context of 'parser.parse_args()' makes the purpose of 'arg' relatively clear

Boolean-Returning Function Without Prefix

The function myLen returns an integer representing a count, but its name is non-standard. If it were intended to return a boolean, it would need a prefix. However, as a length getter, it should follow Pythonic naming conventions like get_length or __len__.

Suggested change

	def myLen(self):
	def get_length(self):

Reasons & Gaps

Reasons

1. Function names should clearly indicate the type of data or action performed
2. 'myLen' is a cryptic abbreviation of 'my length' and lacks a clear verb-noun structure
3. Standardizing naming improves discoverability and reduces cognitive load for developers

Gaps

1. The function returns an integer, so the boolean prefix rule (1.2) technically doesn't apply, but the name is still vague
2. Python's len is the standard protocol for length, but the user defined a custom method

Non-Standard Variable Naming (camelCase in Python)

The parameter defaultValue uses camelCase, which is inconsistent with Python's snake_case convention. Renaming it to default_value aligns with PEP 8 and the rest of the Python ecosystem.

Suggested change

	def __init__(self, size, defaultValue = None):
	def __init__(self, size, default_value = None):

Reasons & Gaps

Reasons

1. Python naming conventions (PEP 8) specify snake_case for variables and parameters
2. Consistent casing across the codebase prevents confusion and improves professional quality
3. 'default_value' is more expressive and follows standard library patterns

Suggested change

	Index = self.items.index(element)
	index = self.items.index(element)

Reasons & Gaps

Reasons

1. PascalCase is reserved for classes; using it for variables causes semantic confusion
2. Lowercase 'index' is the standard convention for local variables in Python
3. Improving casing consistency makes the code easier to scan and maintain

	return self.head == None
	def is_empty(self):
	return self.head == None

Reasons & Gaps

Reasons

1. Boolean returning functions require a prefix like 'is_' for clarity
2. Improves readability by signaling the expected return type to callers

Reasons & Gaps

Reasons

1. 'temp' is explicitly listed as a forbidden generic name in standards
2. Descriptive names like 'new_node' clarify the variable's intent
3. Reduces cognitive load when reading data structure manipulation logic

Reasons & Gaps

Reasons

1. Functions returning booleans should use prefixes like 'is_' or 'has_'
2. 'search' implies finding an object, while the return is a boolean
3. Prefixing makes the API more intuitive for conditional statements

Gaps

1. 'search' is a common verb for this action in data structures

Reasons & Gaps

Reasons

1. Python naming conventions (PEP 8) require variable names to be in snake_case
2. Consistent casing reduces cognitive load and follows community standards
3. PascalCase is reserved for class names in Python to avoid confusion

Suggested change

	Input = input('Say Something: ')
	user_input = input('Say Something: ')

Reasons & Gaps

Reasons

1. Variable names should be lowercase with words separated by underscores
2. Avoid naming variables similarly to built-in functions to prevent developer error
3. 'user_input' provides better semantic clarity than the generic 'Input'

Gaps

	self.items = []

Reasons & Gaps

Reasons

1. 'index' usually refers to a position in a list, not the list container itself
2. Using 'items' or 'elements' clearly communicates that the variable holds the stack data
3. Improves maintainability by aligning variable names with their functional purpose

Reasons & Gaps

Reasons

1. Python naming conventions require snake_case for all function and method names
2. Including 'stack' in the method name is redundant as it is a method of the Stack class
3. 'get_size' or 'size' is more concise and follows standard object-oriented patterns

1. Using plural names for single items in a loop can cause confusion about the variable type
2. 'char' is the standard technical abbreviation for a single character in most languages
3. Improving naming consistency reduces cognitive load during code reviews

Gaps

1. 'chars' is a common pluralization and might be considered acceptable by some teams
2. The context of iterating over a string makes the purpose of the variable clear despite the naming

Vague Variable Name

The variable name 'num' is generic. A more descriptive name like 'letter_index' or 'char_position' would better reflect that this value represents a position within the alphabet.

Suggested change

	num = LETTERS.find(chars)
	letter_index = LETTERS.find(chars)

Reasons & Gaps

Reasons

1. 'num' does not convey the semantic meaning of the value being an alphabet index
2. Descriptive names help distinguish between different numeric values in the same scope
3. 'letter_index' explicitly identifies the relationship between the variable and the LETTERS string

Gaps

1. 'num' is technically accurate as it holds an integer index
2. In short algorithmic blocks, generic names for indices are sometimes tolerated

Vague Variable Name

The variable 'choice' is functional but generic. Renaming it to 'operation_mode' or 'user_action' provides better context regarding what the user is choosing.

Suggested change

	choice = input('Encrypt or Decrypt? [E/D]: ')
	operation_mode = input('Encrypt or Decrypt? [E/D]: ')

Reasons & Gaps

Reasons

1. 'operation_mode' describes the intent of the variable within the cipher logic
2. Generic names like 'choice' can become ambiguous as the complexity of the main function grows
3. Specific naming aligns better with domain-relevant terminology for application flow

Gaps

1. 'choice' is a very common name for user input variables in simple scripts
2. The prompt string immediately following the variable makes the context obvious

Vague Verb in Function Name

The function name 'connect' is a generic verb that doesn't fully describe the action. Since it performs a port scan, a name like 'scan_ports' or 'check_host_ports' is more appropriate.

Suggested change

	def connect(host):
	def scan_ports(host):

Reasons & Gaps

Reasons

1. Generic verbs like 'connect' lack the specific noun required for clarity
2. 'scan_ports' explicitly defines the function's intent to iterate over multiple ports
3. Improved naming acts as internal documentation for the script's behavior

Gaps

1. The function name is technically accurate as it attempts to connect to ports
2. Context within a port scanner script makes the purpose relatively clear

Language-Specific Case Convention Violation

In Python, variable names should follow the snake_case convention. 'userInput' uses camelCase, which is inconsistent with PEP 8 standards.

Suggested change

	userInput = input('Enter the Server address(URL) to check for open ports: ')
	user_input = input('Enter the Server address(URL) to check for open ports: ')

Reasons & Gaps

Reasons

1. PEP 8 explicitly recommends snake_case for variable and function names in Python
2. Consistent casing prevents confusion when integrating with other Python libraries
3. Adhering to language idioms is a core part of professional software development

Gaps

1. CamelCase is functional and common for developers coming from Java/JavaScript backgrounds
2. The variable name itself is descriptive and clear despite the casing style

Language-Specific Case Convention Violation

The variable 'remoteServerIP' uses camelCase and contains an uppercase abbreviation 'IP'. Python standards prefer snake_case like 'remote_server_ip'.

Suggested change

	remoteServerIP = socket.gethostbyname(userInput)
	remote_server_ip = socket.gethostbyname(user_input)

Reasons & Gaps

Reasons

1. Snake_case is the standard convention for Python variables to ensure readability
2. Mixing casing styles (camelCase vs snake_case) makes the codebase harder to scan
3. Standardizing on 'remote_server_ip' aligns with the Python ecosystem's best practices

Gaps

1. 'IP' is a standard technical abbreviation and often kept uppercase in many styles
2. The name is highly descriptive and unlikely to cause functional issues

Non-Descriptive Function Name

The function name 'parentData' is vague and uses camelCase, which is not idiomatic for Python. A more descriptive name like 'send_parent_data' or 'handle_parent_pipe_communication' in snake_case would better reflect its purpose.

Suggested change

	def parentData(parent):
	def send_parent_data(parent):

Reasons & Gaps

Reasons

1. Function names should explicitly state the action performed using a verb-noun pattern
2. Python convention (PEP 8) requires snake_case for function and variable names
3. 'parentData' does not clearly communicate that it sends data through a pipe

Gaps

1. The function name is partially descriptive but lacks a clear verb indicating action
2. Project-specific naming conventions might allow camelCase, though PEP 8 discourages it

Non-Descriptive Function Name

The function name 'childData' is vague and uses camelCase. Renaming it to 'send_child_data' using snake_case would improve clarity and follow Python naming standards.

Suggested change

	def childData(child):
	def send_child_data(child):

Reasons & Gaps

Reasons

1. Descriptive names reduce cognitive load by explaining the function's intent
2. Standardizing on snake_case ensures consistency with the Python ecosystem
3. 'send_child_data' explicitly defines the operation being performed on the pipe

Gaps

1. The name is contextually understandable within this small script but lacks a strong verb
2. Naming consistency with the previous function is maintained but both are non-standard
