如何将毫秒的时间戳转换为日期时间？

Question

I am using Google Drive API to download some files but unable to convert its datetime into Python datetime:

 '2022-04-23T15:38:11.588Z' does not match format '%Y-%m-%dT%H:%M:%SZ'

I thought this would work:

 datetime.strptime(meta["modifiedTime"], '%Y-%m-%dT%H:%M:%SZ'))

How can I do this?

Answer 1

All but the final letter Z is isoformat, so we can just do:

 from datetime import datetime d = '2022-04-23T15:38:11.588Z' print(datetime.fromisoformat(d[:-1]))

Output:

 2022-04-23 15:38:11.588000

Alternative:

 from dateutil.parser import isoparse print(isoparse(d)) # Output: 2022-04-23 15:38:11.588000+00:00

Answer 2

Because the seconds you are getting from the Google Drive API time, is in float type format. So instead of just doing %SZ , you can specify %S.%fZ that will now read the seconds in float.

 from datetime import datetime date = '2022-04-23T15:38:11.588Z' print(datetime.strptime(date, '%Y-%m-%dT%H:%M:%S.%fZ'))
