Output: The list of most frequent days sorted by the order of days in week (from Monday to Sunday).

Solution:

from calendar import weekday, day_name

def most_frequent_days(year):

    for day in sorted( {weekday(year, 1, 1), weekday(year, 12, 31)} ):
        return [ day_name[day]  ]

print(most_frequent_days(2023))
