HackerRank Write a function problem solution in python

In this HackerRank write a function problem solution in python, we need to develop a python program in which we need to complete a function that can check whether a year is a leap year or not.

Problem solution in Python 2 programming.

def is_leap(year):
    leap = False
    
    # Write your logic here
    if (year % 100 == 0) and (year %400 != 0):
        leap = False
    elif (year % 4 == 0):
        leap = True
    return leap
