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.
