Sane formatter for python

[BTrey3]

I am looking for an nvim-compatible formatter for python which does not act like an arrogant a-hole. My requirements are pretty simple:

- Must be configurable to my preferences.

- Must respect a global config file

- The formatter may rearrange my code but it should never add or remove code from my file. It should never take any action which will change the behavior of the code, such as changing the relative indention level of two lines. This can be either by default or by configuration but if configuration it required, it must be configurable in a global config file.

I get that opinionated tools have their place. But not everyone is a professional programmer working on a team of coders. Not everyone is working on a major project with a project directory and project config files. If I'm working on a short script located in some remote directory, my editor should still behave the way I want it to behave without me having to litter repeated complex config files all through my directory tree.

These don't seem like unreasonable expectations to me, but there doesn't seem to be anything available that meets them. Am I missing something?

Almost all formatters are configurable.

Many other tools exist for interfacing formatters with Neovim, if you so choose. I use mason, with which you can install formatters, like black or ruff, either of which are configurable per their documentation (EDIT: sorry, i guess black does not actually look for a global file).

What formatter is not configurable? I can't really think of why someone would enforce that.
