Week 1: Types, condition clauses and loops/11. Leap year?

'''
Write a program that asks the user for the year and indicates whether the given year is a leap year or not.

A year is a leap year if it is evenly divisible by four.
However, a year divided by 100 is a leap year only if it is also divided by 400.


So, for example, 2000 and 2004 are leap years, but 1900 is not.

Example output 1:
Give a year: 1984
Is a leap year


Example 2:
Give a year: 1983
Not a leap year
