3. If Else If Statement:

When we need to check for multiple conditions to be true then we use elif Statement.

This statement is like executing a if statement inside a else statement.

else:
    Body  

Example:

a = 10
if a >= 20:
    print('Condition is True')
elif a >= 15:
    print('Checking second value')
else:
    print('All Conditions are false')
