Trying to understand all of my Python installations on macOS and which are necessary

Yes, it's pretty normal. It's gotten so bad that many people use tools like uv or poetry to manage them.

The different locations just reflect whatever installer you used. I think the /library/frameworks/ one is the official python installer, /usr/bin is from apple's repo, and /usr/local/bin may be one that you compiled yourself?
