Catch the Python habits that come back to bite you

## What this does

### Top 3 things it does for you

- Review Python code against a list of known bad practices
- Check an implementation before you call it done
- Trace a bug back to a known bad habit

## About Python Anti-Patterns Checklist

This is a checklist of common Python anti-patterns to look for when reviewing code.

Use it while reviewing someone's code, as a last pass before finalizing your own implementation, or when you are debugging something that might turn out to be a known bad practice rather than a novel problem.
