Python if...else Statement

If-Else statements in Python are a component of conditional statements.

There are four types of conditional statements in Python:

• The if statement
• The if-else statement
• The if…elif…else Statement
• The nested-if statement

If Statement

The if statement is employed to run a code block when a specific condition holds.

Syntax:

if (condition):
  # block of code to be executed if the condition is true

Example:

Output:

If...else statement

The if.else statement is employed for executing one block of code when a given condition is true and another block of code when the condition is false.

Syntax:

if (condition):  
  # block of code to be executed if the condition is true
else:
  # block of code to be executed if the condition is false

Example:

  print("Number is greater than 5")
else:
  print("Number is not greater than 5")

Output:

if…elif…else Statement

Python's if-elif-else statement runs a block of code between various possibilities.

Syntax:

if(condition1):
 # block of code to be executed if condition1 is true
elif(condition2):
 # block of code to be executed if the condition1 is false and condition2 is true
else:
 # block of code to be executed if the condition1 is false and condition2 is false

Example:

number = 10
if (number > 15):
   print("Number is greater than 15")
elif (number > 10):
   print("Number is greater than 10 but less than or equal to 15")
else:
   print("Number is equal to 10")

Output:
