Python Program to Check Leap Year

Problem: Write a program in python to check whether a year is a leap year or not.

Example:

Input:  2020
Output: Leap Year

Input: 2021
Output: Not a Leap Year

A year is said to be a leap year if it is divisible by 4. It mostly occurs every 4 years but every 100 years we skip a leap year unless it is divisible by 400.

Hence important point to note is that every year which is divisible by 4 is not necessarily a leap year, if the year is divisible by 100 then it should be divisible by 400 to be called a leap year.

Let’s write code in python to check leap year.

Recommended: If else in Python

year = int(input("Enter year: "))

if year%4==0 and year%100 != 0:
    print("Leap Year")
elif year%400 == 0:
    print("Leap Year")
else:
    print("Not a Leap Year")

Output:

Enter year: 2020
Leap Year
