The cosmo monorepo currently vendors Python 3.6, since cosmo originally didn't have threads support and that was the last version before threads became mandatory. I'm pretty happy with the old version since I've been using Django since the 2000's. I put a lot of work into enhancing monorepo cosmo python with things like a better REPL that works across platforms. It may not be supported by the Python team, but it's supported by me. However the future will probably be building Python w/ Cosmo outside the monorepo. See the other comments for details on how to use APE + Python 3.11 for a modern experience.
