datetime from string in Python, best-guessing string format

Question

The function to get a datetime from a string, datetime.strptime(date_string, format) requires a string format as the second argument. Is there a way to build a datetime from a string without without knowing the exact format, and having Python best-guess it?

Answer 1

Use the dateutil library.

I was already using dateutil as an indispensable lib for handling timezones
(See Convert UTC datetime string to local datetime and How do I convert local time to UTC in Python?)

And I've just realized it has date parsing support:

import dateutil.parser
yourdate = dateutil.parser.parse(datestring)
