I just pushed an addendum, and it is being rendered right now.

Kudos on making the update! Makes sense that you might not find it if you didn't know it was there. Python's "batteries included" means most things you may want to do, you should check to see if there is a standard lib option, as well. Sometimes it is barebones enough that you may want more, of course. So, really nice to see all of the options you presented.
