Added python3.10 to tox environment list

[matthewhegarty]

Problem

Now that python 3.10 is available, I have added it to the list of supported python releases.

Whilst testing this, I noticed tox failures for >= 3.9 only, because support for pytz was dropped in that release. However, since pytz is still a dependency for Django, I added it to the import list in test.txt, since it is required for test_widgets.py.

Solution

• Updated files to reference python 3.10.

Acceptance Criteria

Ran full tox run through locally.

Coverage remained the same at 98.073% when pulling c167156 on matthewhegarty:python-3-10-update into 125c1cf on django-import-export:main.

Hi @matthewhegarty, looks the tests are not passing due to DeprecationWarning. Also not all tests are run, is this because one test failed?

Would you mind creating your branches in this repository instead of in your fork? I could try some commits to this branch when/if I have spare time :)

Thanks!

Hi Manel, thanks for taking a look. I've marked it as draft because the issue is that the distutils library is deprecated in 3.10 but current Django releases still use it. The solution would be to only run tests if using the Django main branch when python version is 3.10. I haven't got round to fixing that yet.

Have updated the "exclusion" matrix, so now python3.10 will only be used against Django main.

@manelclos I believe this is ok to be merged now - would you mind checking?

LGTM

Marked as draft until I can successfully test manually on 3.10
