I only want something with slightly less friction than a jupyter notebook but better for controlled editing that an ipython shell. Something that doesnt make any files on my filesystem or anything else that I have to clean up later. That's why I'm looking for an online repl!

Okay, I can live with having to be logged in because it keeps me logged in for a long time, but do I really need to figure out what I want to call this "project" which is two functions and a print that I never want the world to see?

For a few glorious years, repl.it was exactly what I wanted when it came to writing derpy little one-off functions.
