There's no need for the `datetime` as you've imported `date` directly into the namespace. Correct that problem and you'll still fail as you're passing strings instead of integers. I'd just force your `monthdate` to be MMDD and pass that into `strptime` with `year`.
>>> year = '2018' >>> monthdate = '0211' # skipping the input code. >>> from datetime import datetime >>> datetime.strptime(year + monthdate, '%Y%m%d') datetime.datetime(2018, 2, 11, 0, 0) >>> datetime.strptime(year + monthdate, '%Y%m%d').weekday() 6 -- My fellow Pythonistas, ask not what our language can do for you, ask what you can do for our language.
