Using Pip On Repl.it
Repl.it allows you to easily load Python modules that are on PyPi, but I needed to write some code that relied on a Python module hosted on GitHub specifically (long story short: it's a temporary fork of another Python package, and I didn't feel it would be necessary to deploy it up onto PyPi). So I wound up doing some weird stuff to wind up using that Python package hosted on GitHub.
You can read my blog post to explain the weird stuff that I did: https://tra38.github.io/blog/using-pip-on-repl-it.html
Here is my final Repl (https://repl.it/@tra38/LittleNiftySubweb-Experimental\) where I successfully loaded up my Python package from GitHub.
I hope this experience will be useful for you if you wind up needing to do something like this!
