Development

If you want to contribute anything to |parso|, just open an issue or pull request to discuss it. We welcome changes! Please check the CONTRIBUTING.md file in the repository, first.

Deprecations Process

The deprecation process is as follows:

1. A deprecation is announced in the next major/minor release.
2. We wait either at least a year & at least two minor releases until we remove the deprecated functionality.

Testing

The test suite depends on pytest::

pip install pytest

To run the tests use the following::

pytest

If you want to test only a specific Python version (e.g. Python 3.9), it's as easy as::

python3.9 -m pytest

Tests are also run automatically on GitHub Actions <https://github.com/davidhalter/parso/actions>_.
