Create a function get_days that takes two dates and returns the number of days between the first and second date.
get_days(
datetime.date(2019, 6, 14), # June 14, 2019
datetime.date(2019, 6, 20) # June 20, 2019
) ➞ 6
get_days(
datetime.date(2018, 12, 29), # December 29, 2018
datetime.date(2019, 1, 1) # January 1, 2019
) ➞ 3
# Dates may not all be in the same month/year.
get_days(
datetime.date(2020, 5, 24),
datetime.date(2019, 5, 24))
) ➞ -366
# Backwards dates should return a negative change.
