How to convert time object to datetime object in python? [duplicate]

Question

I have timestamp which is a time object and trying to convert it to a datetime object because datetime has stonger capabilities and I need to use some function that only datetime has.
The reason I'm starting with time is because datetime doesn't support milliseconds which the original string contains.

What is the easiest way to do it?

"because datetime doesn't support milliseconds - what makes you think that? Just because there is no attribute "milliseconds" doesn't mean you cannot work with them - just multiply by 10^3 and use the microseconds attribute ;-) — FObersteiner

docs.python.org/3/library/time.html#time.strftime time.strftime doesn't support printing milli or microsecond. unlike datetime.strftime docs.python.org/3/library/… . (and the same about strptime..) — kaki gadol

your question says nothing about strftime. please clarify if this should be helpful for others. — FObersteiner

btw. there also seems to be confusion about datetime and time objects vs. the modules with the same name. There is e.g. a datetime.time class, where you can use strftime without problems to create a string with milliseconds precision: datetime.time(1,2,3,444000).strftime('%H:%M:%S.%f')[:-3] — FObersteiner

I referred it as time object because it's the return value of time.strptime.. BUT, you are right.. I'll flag the question as duplicate. Thanks for the interesting discussion — kaki gadol

assuming timestamp is an time object and datetimestamp will be the datetime object:

from datetime import datetime
import time

timestamp = time.strptime('2022-03-02 02:45:12.123', '%Y-%m-%d %H:%M:%S.%f')
datetimestamp = datetime(*timestamp[:5])

It works because time is actually a tuple with the following structure (year, month, day, hour, minute, seconds....), and the datetime __init__ expects the same sequence of variables

timestamp is a time.struct_time object for clarification. But why not simply datetimestamp = datetime.fromisoformat('2022-03-02 02:45:12.123') ?
