Conditional Statements

Conditional statements are usually wrritten in if....else.... blocks, where if the condition returns a true value then the "if block" will execute, else "else block" will be executed.

If...Else...

a = 10
b = 25

if b > a:
    print("b is greater than a")

else:
    print("a is greater than b")

Output :

b is greater than a

elif...

In case, User have more than one condition, "elif" (Else If) blocks are used

Example :

age = int(input("Enter your age : ")) #Takes user's age as input.

if age >= 18 :
    print("You are eligible to vote")

elif 0 > age < 18 :
    print("Try again, after you are 18+")

else :
    print("Enter a valid age") #for negative inputs

Output :
for age = 20 :

You are eligible to vote

for age = 15 :

Try again, after you are 18+

for age = -16

Enter a valid age

Mostly used operators

Operator	Operation	Example
+	Addition	x + y
-	Subtraction	x - y
*	Multiplication	x * y
/	Division	x / y
//	Floor Division	x // y
**	Exponentiation	x ** y
%	Modulus	x % y
==	Equal	x == 5
!=	Not equal	x != y
>	Greater than	x > y
<	Lesser than	x < y
>=	Greater than or equal to	x >= y
<=	Less than or equal to	x <= y
and	Returns True if both statements are true	x = y and x = 5
or	Returns True if one of the statements is true	x = y or x = 5
not	Reverse the result, returns False if the result is true	not(x = y and x = 5)
