Another notification:
I use generator grammar, which indicates it only supports python >= 3.8.
Owner, edit it, please!!!!!!!

looked around for Al Sweigart's style guide, couldn't find an existing formatter. Despite that, noticed some styling differences. Please correct:

• naming from using underscore to using hyphenation, as seen in Pyth..mes/barebones/bagels-barebones.py, etc.
• please squash the two commits and name them something that indicates what will do to the repository's stage, e.g. Add liars-pub.

Note: Your commit log isn't for you, it's for the person (it might be you!) who comes to inspect the code either because it's getting changed or it's getting added to. So it needs to be clear from the commit history what happened in each commit.

There may be issues with logic but I was only able to give a cursory look.
