[FIXED] Slice two datetime objects with Python

Issue

I have two date time objects in Python 2.7.

The first looks like this:

2018-09-22 00:00:00

and the second looks like this:

1899-12-30 17:20:59

I would like to end up with the dates from the first datetime object and the time from the second datetime object.

2018-09-22 17:20:59

Unfortunately I am coding for some old GIS software and compelled to use 2.7 Any help is appreciated.

Solution

Have a look at datetime.datetime.replace() and datetime.datetime.combine() methods:

>>> from datetime import datetime
>>> dt1 = datetime.strptime('2018-09-22 00:00:00', '%Y-%m-%d %H:%M:%S')
>>> dt2 = datetime.strptime('1899-12-30 17:20:59', '%Y-%m-%d %H:%M:%S')
>>> dt3 = dt1.replace(hour=dt2.hour, minute=dt2.minute, second=dt2.second)
>>> dt3
datetime.datetime(2018, 9, 22, 17, 20, 59)

# or even better
>>> dt4=datetime.combine(dt1.date(), dt2.time())
>>> dt4
datetime.datetime(2018, 9, 22, 17, 20, 59)
