-> 🚀 **IMPORTANT: The official psf/black action has been released!**
-> Since `psf/black` has been released, the action in this repository is not trivial anymore. Therefore, you are advised to use the [official black](https://black.readthedocs.io/en/stable/integrations/github_actions.html) action. Some features in this action are not in the official action. The differences between the two actions are documented in <https://github.com/rickstaa/action-black/issues/10>. Please open a [pull request](https://github.com/rickstaa/action-black/pulls) if you think features are missing.

 This action runs the [black formatter](https://github.com/psf/black) to check/format your python code on a push or pull request. It is similar to [reviewdog/action-black](https://github.com/reviewdog/action-black) that can annotate the black changes required with [Reviewdog](https://github.com/reviewdog/reviewdog). However, this version also allows you to format the code using GitHub actions (see #advanced-use-cases).
