given_date = datetime.today().date()
print("\nGiven date:", given_date, " --> Last day of month:", last_day_of_month(given_date))

given_date = datetime(year=2008, month=2, day=1).date()
print("\nGiven date:", given_date, " --> Last day of month:", last_day_of_month(given_date))

given_date = datetime(year=2009, month=2, day=1).date()

  1. I want to add these values of first and last day of the month to a dictonary. After adding these values when I print the dictionary it shows last day as( ‘last day’: datetime.date(2020, 8, 31)). Any suggestions on how this can be fixed
