# set the firstweekday to 1
cal = calendar.Calendar(firstweekday = 1)
year = 1994
month = 9

print("Iterating over the weeks of September 1994 where each tuple is date, month and year and iterator starts with firstweekday as Tuesday")
for i in cal.itermonthdays3(year, month):
    print(i)
print()
print()
