Python Formatting

There is a variety of style checkers (tools that give a feedback) and auto-formatters (tools that are able to fix the formatting violations automatically).

Existing Type Checkers and Auto-Formatters

pycodestyle

Checks Python code against some style conventions in PEP 8.

autopep8

Automatically fixes most of the formatting issues reported by pycodestyle. Since PEP 8 is rather liberal, autopep8/pycodestyle don't modify code too much.

Black

A PEP 8 compliant opinionated auto-formatter with its own style, going further than autopep8/pycodestyle. Style configuration options are deliberately limited to a minimum. Black aims for readability and reducing git diffs. Black is an easy-to-use tool, with sensible and useful defaults. Its style is very elegant.

Ruff

Besides being a linter, Ruff is also an auto-formatter. It is designed as a drop-in replacement for Black.

yapf

Auto-formatter that can be configured to support different styles.

isort

Sorts import statements alphabetically, and separates them into sections, according to their type.
