Question

Language: PYTHON

Function name : favorite_day
Parameters : list of tuples (dates), int (weekday, 0-6, Mondays are 0),
int (day of the month 1 to 28)
Returns: dates: list of tuples
Description: Imagine that you have a favorite weekday, and want to see if certain days fall on that weekday. Using the calendar module from the Python standard library , write a function which takes in a list of tuples formatted like [(month, year), etc.], your favorite weekday, and a day of the month. Using the module, find the weekday of each (month,year) tuple at the day of the month that was passed in (1-28). If that weekday is equal to your favorite weekday, add the tuple to a list to be returned at the end of your code. Assume the day of the week will lie within 0-6 inclusive and the day of the month will be always be valid.

(Hint: look at calendar.weekday method)

Test Cases:

>>> dates = [(1, 1999), (7, 1980), (3, 2018), (12, 2003)] >>> print(favorite_day(dates, 6, 20))
[(7, 1980)]

>>> dates = [(10, 1803), (1, 2019), (6, 1964), (11, 1920), (2, 2011)] >>> print(favorite_day(dates, 0, 1))
[(6, 1964), (11, 1920)]

Answer 1

#look for the indentation

CODE:

import calendar

def favorite_day(dates, week_day, day):
    match_weekday = []
    # looing on the list
    # i, j have the values in months, years

    for i, j in dates:
        #calendar.weekday(year, month)
        if calendar.weekday(j, i, day) == week_day:
            match_weekday.append((i, j))
    # return the list
    return match_weekday

dates = [(10, 1803), (1, 2019), (6, 1964), (11, 1920), (2, 2011)]
print(favorite_day(dates, 0, 1))

# dates = [(1, 1999), (7, 1980), (3, 2018), (12, 2003)]
# print(favorite_day(dates, 6, 20))
# [(7, 1980)]
