CYB/130 Week 4 Python LAB 5.21: Leap year – functions
A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are:
1) The year must be divisible by 4
2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400
Some example leap years are 1600, 1712, and 2016.
Write a program that takes in a year and determines whether that year is a leap year.

Ex: If the input is:
1712
the output is:
1712 is a leap year.

Ex: If the input is:
1913
the output is:
1913 is not a leap year.

Your program must define and call the following function. The function should return true if the input year is a leap year and false otherwise.
def is_leap_year(user_year)

Note: This is a lab from a previous chapter that now requires the use of a function.
