Format a datetime into a string with milliseconds

How can I format a datetime object as a string with milliseconds?
To get a date string with milliseconds, use [:-3] to trim the last three digits of %f (microseconds): >>> from datetime import datetime >>> datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f')[:-3] '2022-09-24 10:18:32.926' Or shorter: >>> from datetime import datetime >>> datetime.utcnow().strftime('%F %T.%f')[:-3] '2022-09-24 10:18:32.926' See the Python docs for more "%" format codes and the strftime(3) man page for the full list.
