Eliminate the excess, leaving only the date. At the same time, save y test1datatime type

Answer 1

Eliminating the excess, leaving only the date. At the same time, keep the datatime type of test1

Determine exactly what you need.
datetime contains time information. If you don’t need it there, then use the datetime.date type.
If you need to reset the time information, then use combine
. ..

date1 = datetime.datetime.fromisoformat('2021-09-08 15:45:40.260000+00:00')
# datetime.datetime(2021, 9, 8, 15, 45, 40, 260000, tzinfo=datetime.timezone.utc)

date1.strftime('%Y-%m-%d')
# '2021-09-08'

date1.date()
# datetime.date(2021, 9, 8)

date1.date().isoformat()
# '2021-09-08'

datetime.datetime.combine(date1.date(), datetime.datetime.min.time())
# datetime.datetime(2021, 9, 8, 0, 0)
