python time + timedelta equivalent

Question

I'm trying to do something like this:

time() + timedelta(hours=1) 

however, Python doesn't allow it, apparently for good reason.

Does anyone have a simple work around?

Answer 1

The solution is in the link that you provided in your question:

datetime.combine(date.today(), time()) + timedelta(hours=1) 

Full example:

from datetime import date, datetime, time, timedelta  dt = datetime.combine(date.today(), time(23, 55)) + timedelta(minutes=30) print dt.time() 

Output:

00:25:00 

Answer 2

If it's worth adding another file / dependency to your project, I've just written a tiny little class that extends datetime.time with the ability to do arithmetic. If you go past midnight, it just wraps around:

>>> from nptime import nptime >>> from datetime import timedelta >>> afternoon = nptime(12, 24) + timedelta(days=1, minutes=36) >>> afternoon nptime(13, 0) >>> str(afternoon) '13:00:00' 

It's available from PyPi as nptime ("non-pedantic time"), or on GitHub: https://github.com/tgs/nptime
