DIRECTORY.md not being updated by TravisCI

[chttrjeankr]

• .travis.yml isn't updating DIRECTORY.md automatically as it should
• scripts/build_directory_md.py needs can have some minor changes too. minor changes in format of DIRECTORY.md #1461

If you can make Travis CI write back to the incomming pull request, that would be cool. Writing back to master might put Travis into an infinite loop. @jneeven is doing some magic in lgeiger/black-action#2 but that is based on GitHub Actions, not Travis CI.

A fix for the DIRECTORY.md, can't get Travis CI to push back to the initiating PR. #1542

https://github.com/TheAlgorithms/Python/blob/master/.github/workflows/autoblack.yml Is writing changes back to a PR. GitHub Actions Beta ends in two weeks and then it will go live.

Nice! That looks very close to the same changes I was making to the travis.yml. When the GH Actions is released I'll make the updates. Thanks @cclauss

[cclauss]

See if they will let you into the beta... https://github.com/features/actions

[mrvnmchm]

Should I make any changes to #1549, or do I just need another peer review?

Writing back to a PR is NOT allowed in GitHub Actions. See the other workflow to see how to use push instead.

[chttrjeankr]

This occurs now:
when there's nothing to commit

[cclauss]

This should remain open until #1572 lands.
