# Python program to illustrate the 
# use of itermonthdays2() method

# import class
import calendar

# Creating Calendar Instance
cal = calendar.Calendar()
year = 2009
month = 2

print("Iterating over the weeks of February 2009 where each tuple is date and weekday on that day")
print("Days outside the month are written as 0")
print("Iteration starts from weekday/second value as 0, ie, Monday")
for i in cal.itermonthdays2(year, month):
    print(i)
# first value is the day of the month; 
# days outside of the month is 0
# second value is weekday number where 
# Monday is 0 till Sunday which is 6
print()
print()

# set the firstweekday to 4
cal = calendar.Calendar(firstweekday = 4)
year = 2020
month = 1

print("Iterating over the weeks of January 2020 where each tuple is date and weekday on that day")
print("Iteration starts from weekday/second value as 4, ie, Friday")
for i in cal.itermonthdays2(year, month):
    print(i)
print()
print()
