Python Error : unsupported operand type(s) for +: 'int' and 'datetime.timedelta'

问题

I have written a function in python that accepts a timestamp and return the timestamp w.r.t to the current timezone.

Code

def datetime_from_utc_to_local(utc_datetime):
    now_timestamp = time.time()
    offset = datetime.fromtimestamp(now_timestamp) - datetime.utcfromtimestamp(now_timestamp)
    return utc_datetime + offset

Error:

unsupported operand type(s) for +: 'int' and 'datetime.timedelta'

Can you please help me fix this error.

I want this function to return the timestamp

回答1:

offset is a datetime.timedelta object. If you need just the seconds, extract them with timedelta.total_seconds():

return utc_datetime + offset.total_seconds()

Your function signature however, suggests it was expecting you to feed it a datetime.datetime() object, in which case you shouldn't change this function, but the code that calls it. Clearly you are giving it an integer instead.
