Convert python datetime to timestamp in milliseconds

Question

How to convert a human readable time with the format 20.12.2016 09:38:42,76 to Unix timestamps in milliseconds? I found a lot of similar questi

Answer 1

For those who searches for an answer without parsing and loosing milliseconds, given dt_obj is a datetime:

python3 only, elegant

int(dt_obj.timestamp() * 1000)

both python2 and python3 compatible:

import time

int(time.mktime(dt_obj.utctimetuple()) * 1000 + dt_obj.microsecond / 1000)
