Subject: [Dateutil] Retrieving format string from parsed string
Message-ID: <CAMEbTT4HbD7S9yMp+44cy0qtpt7QNHfOE9GqWoEBS0YmgLWu3A@mail.gmail.com>

Hello,

I was wondering if it is possible to retrieve the inferred format string
from a parsed date str. For example, if I parse a str as follows:

import dateutil
mystr = '1990/04/22'
parsed = dateutil.parser.parse(mystr)

Is there any way to retrieve 'YYYY/MM/DD'? I'm assuming the returned
datetime object doesn't retain the information.

I would appreciate any help that you could offer.

Thank you,
Bart

Unfortunately it is not at this time:

https://github.com/dateutil/dateutil/issues/125

This improvement is part of a more general improvement to the parser that I'd like to work on soon. It's a bit trickier than just outputting something that can be parsed by strptime, because dateutil's parser can infer dates in formats that are not compatible with strptime (mostly to do with time zones).

OK, thank you. I've subscribed to the github issue. It makes sense why
that would be quite difficult!
