Convert datetime.time into datetime.timedelta in Python 3.4 -

i trying convert 2 "durations", receiving typeerror due 1 being datetime.timedelta , 1 being datetime.time:

typeerror: unorderable types: datetime.time() <= datetime.timedelta() 

what efficient way convert datetime.time datetime.timedelta?

i have checked docs , there no built-in method conversion between these 2 types.

datetime.time() not duration, point in day. if want interpret duration, convert duration since midnight:

datetime.combine(date.min, timeobj) - datetime.min 

demo:

>>> datetime import datetime, date, time >>> timeobj = time(12, 45) >>> datetime.combine(date.min, timeobj) - datetime.min datetime.timedelta(0, 45900) 

you may need examine how datetime.time() object in first place though, perhaps there shorter path timedelta() input data have? don't use datetime.time.strptime() durations, example.
