Using functions from examples 3, 4 & 5, write functions to:
Calculate the difference between two dates in days.
Calculate which day in the week corresponds to a certain date
given another date and its corresponding day of the week.
![Example (3)
Write a function which takes 1 argument (a year) and
returns True if year is leap, or False otherwise.
def isYearLeap (year):
if year%400==0: return True
if year%4==0 and year%100!=0: return True
return False
print (isYearLeap (2000))
print (isYearLeap (2016))
# Output: True
# Output: True
# Output: False
# Output: False
print (isYearLeap (1900))
print (isYearLeap (2019))
