def is_leap(year):

leap = False

A leap year program in python is a program that determines whether a given year is a leap year or not.

A year is a leap year if it is divisible by 4. But, years divisible by 100 are not leap years, unless they are also divisible by 400.

For example:

The years 1700, 1800, and 1900 were not leap years.

But the years 1600 and 2000 were.

import datetime

def is_leap(year):

leap = False

if 1900<= year <= 10**5: if year % 4 == 0: if year % 100 == 0: if year % 400 == 0: leap = True else: leap = True return leap year = int(input())
