Find Monday's date with Python

Question

How do I find the previous Monday\'s date, based off of the current date using Python? I thought maybe I could use: datetime.weekday() to do it, but I am gettin

Answer 1

For future googlers who show up on this page looking for a way to get "the most recent Sunday", rather than "the most recent Monday", you need to do some additional math because datetime.weekday() treats Monday as the first day of the week:

today = datetime.date.today()
weekday = today.weekday() + 1
start_day = today - datetime.timedelta(days=weekday % 7)

If today is Tuesday, this sets start_day to last Sunday. If today is Sunday, this sets start_day to today. Take away the % 7 if you want "last Sunday" to be a week ago if it's currently Sunday.
