[Docs Request]: python_version when unspecified

[jamesbraza]

Overview

python_version shows up in the docs in a few places:

• https://github.com/dosisod/refurb/blob/v1.22.1/docs/configs/default.toml#L9
• https://github.com/dosisod/refurb/blob/v1.22.1/docs/configs/reference.toml#L25
• https://github.com/dosisod/refurb/tree/v1.22.1#setting-python-version

It would be good to document what version it will use, when unspecified.

Proposal

It would be nice if the defaults for python_version would fall back on:

• Match the current interpreter's version
• .python-version from pyenv (like GitHub actions/setup-python does)
• project.requires-python in pyproject.toml

[dosisod]

Thank you for opening this! When unspecified, Refurb uses the current interpreter version. Refurb does not look at the .python-version or pyproject.toml files for versions, though having an option to do this could be useful.

I'll update the docs to reflect the current behavior, and look into adding a flag to default to the min version in pyproject.toml/.python-version in the future.
