Obtain the datetime object for the previous day at midnight

Question

I have a datetime object in Python, for, let's say, 25/06/2017 11:22:33. I'd like to find a pythonic way of getting a datetime object from that one that would represent 24/06/2017 00:00:00.

I can think of:

day_before = now - datetime.timedelta(days=1,
                                      hours=now.hour,
                                      minutes=now.minute,
                                      seconds=now.second)

But I was wondering if there is a more concise way.

Answer 1

from datetime import date, timedelta
yesterday = date.today() - timedelta(1)

From here.
