I don't think it's Jetbrain's fault, even though I have not used their products for almost a decade. Python ecosystem is finicky - too many options - it's hard to decide which things you want and need - black or yapf or ruff, flake8, rope, mypy, pydocstyle, pylint, jedi; there are multiple lsp server options (none of which is ideal), you get to know things like what the heck 'preload' plugin is - the docstring for lsp-pylsp-plugins-preload-enabled just says "Enable or disable the plugin", etc.
Trying to bootstrap a Python setup "that just works™" is also a common struggle e.g. in Emacs world. Python tools are just a bunch of contraptions built with fiddlesticks and bullcrap. Anyone who tells you differently either already have learned how to navigate that confusing world and totally forgot "the beginner's journey"; or too new and have not tussled with its tooling just yet; or simply don't know any better.
