What's the simplest way to subtract a month from a date in Python?

Question

If only timedelta had a month argument in it\'s constructor. So what\'s the simplest way to do this?

EDIT: I wasn\'t thinking too hard about this as was poin

Answer 1

Returns last day of last month:

>>> import datetime
>>> datetime.datetime.now() - datetime.timedelta(days=datetime.datetime.now().day)
datetime.datetime(2020, 9, 30, 14, 13, 15, 67582)

Returns the same day last month:

>>> x = datetime.datetime.now() - datetime.timedelta(days=datetime.datetime.now().day)
>>> x.replace(day=datetime.datetime.now().day)
datetime.datetime(2020, 9, 7, 14, 22, 14, 362421)
