## What it is
autopep8 is a Python tool that automatically formats Python code to conform to the PEP 8 style guide. It uses pycodestyle to detect formatting issues and can fix most of them, either in place or via diff output.

## Use cases
- format python code to pep 8
- auto fix pycodestyle violations
- clean up python code style automatically
- reformat python files before committing
- fix indentation and spacing in python code

## When to choose
- you want automated PEP 8 compliance for Python codebases
- you need to fix pycodestyle-reported issues without manual editing
- you want a lightweight formatter tightly aligned with pycodestyle rules

## When to avoid
- you prefer a faster, more opinionated formatter like Black or Ruff
- you need formatting beyond PEP 8 style rules
- you want a formatter that also enforces linting beyond style issues

## Facets
- artifact type: cli-tool
- maturity: stable
- function: formatter, linter, cli
- domain: developer-tools, programming-languages
- platform: python, cli, cross-platform
- tags: pep8, code-formatting, pycodestyle, python, command-line
