HackerRank Write a function problem solution in python

In this HackerRank write a function problem solution in python, An extra day is added to the calendar almost every four years as February 29, and the day is called a leap day. It corrects the calendar for the fact that our planet takes approximately 365.25 days to orbit the sun. A leap year contains a leap day.

Given a year, determine whether it is a leap year. If it is a leap year, return the Boolean True, otherwise return False.

Note that the code stub provided reads from STDIN and passes arguments to the is_leap function. It is only necessary to complete the is_leap function.

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

Problem solution in Python 3 programming.

def is_leap(year):
    leap = False

                leap = True
            else:
                leap = False
        else:
            leap = True
    else:
        leap = False
    
    return leap
