First off, thanks for contributing to the maintenance of the Python programming language and the CPython interpreter! Even if your contribution is not ultimately accepted, the fact you put time and effort into helping out is greatly appreciated.
Please read the devguide for guidance on how to contribute to this project. The documentation covers everything from how to build the code to submitting a pull request. There are also suggestions on how you can most effectively help the project.
Please be aware that our workflow does deviate slightly from the typical GitHub project. Details on how to properly submit a pull request are covered in Lifecycle of a Pull Request. We utilize various bots and status checks to help with this, so do follow the comments they leave and their "Details" links, respectively.
The final key part of our workflow is that all discussions that are not directly related to the code in the pull request should happen on GitHub Issues, generally in the pull request's parent issue.
Due to the fact that this project is run by volunteers, unfortunately we cannot make any guarantees as to if or when a core developer will get around to reviewing your pull request. If no core developer has done a review or responded to changes made because of a "changes requested" review within a month, you can ask for someone to review your pull request via a post in the Core Development Discourse category.
All interactions for this project are covered by the PSF Code of Conduct. Everyone is expected to be open, considerate, and respectful of others no matter their position within the project.
