Python GitHub Actions workflows

Real Python CI workflows from popular open-source projects, each graded on four CI best practices. See how the best ones are set up, then grade your own.

What a strong Python workflow does

The highest-graded Python workflows enable dependency caching on the setup step, cancel superseded runs with a concurrency group, set a job timeout, and pin third-party actions to a commit SHA. Latchkey applies all of these automatically on managed self-healing runners.
