Datestring to date Python

I am trying to parse this string: '2017-02-28T23:00:00.000Z' into a python datetime object.

My code is

ev_begin_date = datetime.datetime.strptime('2017-02-28T23:00:00.000Z','%Y-%M-%dT%H:%M:%S.%Z' )

I get the following error: 

 ev_begin_date = datetime.datetime.strptime('2017-02-28T23:00:00.000Z','%Y-%M-%dT%H:%M:%S.%Z' )

What am I doing wrong ?

try this:

ev_begin_date = datetime.datetime.strptime('2017-02-28T23:00:00.000Z','%Y-%m-%dT%H:%M:%S.%fZ' )

fixed:

  • you originally used %M for the month as well. it should be %m
  • the millisecond part is %f, the Z is literal (it appears in the string)

you can check out strptime's docs for a complete reference on all format options
