Python proper setup for lsp, linter, formatter

[Cyber-Syntax]

I thought it would be good to open the recipe for the Python installation in here. Let's collect the best python installation on Lazyvim and put it in one discussion because a lot of separated discussions really helped me but it would be better to have some examples of full complete setups.

Mine is currently work as expected but it might wrong...

lsp.lua

• Seems like ty cause issue if I don't disable inlay_hints.
