If Else Statements

else - to execute code block if condition is not met.

elif - to check alternative condition if the main one is False.

Syntax

else

if condition : # code to execute if condition is True. else : # code to execute if condition is False.

else if

if condition1 : # code to execute if condition1 is True. elif condition2 : # code to execute if condition1 is False and condition 1 is True. else : # code to execute if condition1 and condition2 are False.

Else Example

Let's look at a program that checks whether speed is above or below the speed limit for cities (50 km/h).

speed = 60 if speed <= 50: print("Below Limit") else: print("Above Limit")

Output:

Above Limit

Since the condition at line 3 is False, the code inside else block executes.

Elif Example

Let's have a program that categorizes a person depending on his/her height.

Rules are the following:

• below 160cm - short
• between 160cm to 185 cm - medium
• above 185 cm - tall

height = 172 if height <= 160: print("short") elif height <= 185: print("medium") else: print("tall")

Output:

medium

Since the condition at line 3 is False and the condition at line 6 is True, the code inside elif block executes.
