How can I update to Python 3.9.1? A dependency in my repl requires version 3.9 and its one of the main dependencies for my project. I tried to do it manually but it doesnt recognize sudo

Edit: Turned out my issue wasn't an outdated python version, but because I accidentally installed asyncio (it's a built-in module) lol.
However, my question still stands in case this comes up in the future.
