# 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

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
if year%4 == 0:
if year%100 == 0:
if year%400 == 0:
leap = True
else:
leap = False
else:
leap = True
else:
leap = False

return leap```

### Problem solution in pypy programming.
