Hints for Programming Assignment 1 (Month Calendar)

It will be useful to write the following functions:
  # The following function takes as input the month as a number
  # and returns the name of the months as a string. For example,
  # name_of_month(5) should return 'May'. If the month number is
  # invalid, the function should return empty string ''
  def name_of_month(month):
    pass

  # The following function takes as input the month and year as inputs
  # and returns the number of days in the month for that year.
  # For example, days_in_month(2,2020) should return 29 and
  # days_in_month(3,2020) should return 31. For invalid inputs, the 
  # function should return -1
  def days_in_month(month,year):
    pass
