Python calendar: How to check if this year is leap year in Python

In Python, we can easily check if a year is leap or not importing calendar and using function isleap.

import calendar

i = calendar.isleap(2016)
print(i)  # True

i = calendar.isleap(2020)
print(i)  # True

i = calendar.isleap(2019)
print(i)  # False

i = calendar.isleap(2000)
print(i)  # True

i = calendar.isleap(2100)
print(i)  # False

2020 is leap year but 2019 is not.
