If else Statement Example

In this tutorial, we will learn if elif else statement in Python. The if..elif..else statement is used when we need to check multiple conditions.

Syntax of if elif else statement in Python

This way we are checking multiple conditions.

if condition:
   block_of_code_1
elif condition_2:
   block_of_code_2
elif condition_3:
   block_of_code_3
..
..
..
else:
  block_of_code_n

Notes:

1. There can be multiple 'elif' blocks, however there is only 'else' block is allowed.
2. Out of all these blocks only one block_of_code gets executed. If the condition is true then the code inside 'if' gets executed, if condition is false then the next condition(associated with elif) is evaluated and so on. If none of the conditions is true then the code inside ‘else’ gets executed.

Python – if..elif..else statement example

In this example, we are checking multiple conditions using if..elif..else statement.

num = 1122
if 9 < num < 99:
    print("Two digit number")
elif 99 < num < 999:
    print("Three digit number")
elif 999 < num < 9999:
    print("Four digit number")
else:
    print("number is <= 9 or >= 9999")

Output:
