As detailed in this forum thread, I am adding an approach to the Poetry Club Door Policy exercise.

/format

[github-actions]

The "Format code" action has started running.

The "Format code" action has finished running.

For security reasons, /format does not trigger CI builds when the PR has been submitted from a fork. If checks were not passing due to code format, trigger a build to make the required checks pass, through one of the following ways:

• Push an empty commit to this branch: git commit --allow-empty -m "Trigger builds".
• Close and reopen the PR.
• Push a regular commit to this branch.
