How can I automate Python package publishing to the Python Package Index (PyPI)?

Automating Python package publishing to PyPI can be achieved by using continuous integration (CI) tools like Travis CI, CircleCI, or GitHub Actions. Start by configuring your CI tool to run on every push to your repository. In the CI/CD pipeline, include the steps to build and test your package.

After a successful build and passing tests, add a deployment step that uses `twine` to publish your package to PyPI. Then, remember to store your PyPI credentials safely as environment variables in your CI/CD tool to maintain project security. With this setup, your package will be automatically published to PyPI whenever changes are pushed to your repository.
