Example repo: using GitHub Actions for CI/CD for a Python project

This is a minimal repo demonstrating the use of GitHub Actions for Continuous Integration (CI) & Continous Deployment (CD) for a Python project.

The GitHub Actions are:

• Tests: Automatically unit test code using unittest from Python's standard library.
• Code coverage: Generate code coverage reports using coverage.py. The reports are automatically uploaded to codecov. The @codecov-commenter bot adds a comment to PR on code coverage status.
• Lint and format code: Lint using pylint. Check code formatting using black. Check type hints using mypy.
• Check docs build: Check Sphinx docs build successfully.
• Deploy docs to GitHub pages: Automatically deploy docs to a GitHub Pages repo upon merges to main branch.
• Upload release to PyPI: Publish the latest version of the package on PyPI when a new GitHub Release is created.

Each of these actions is stored in a YAML file in the .github/workflows directory.

Push Token for Deploying Docs

Action #5 requires setting up a Personal Access Token with full repo access via the Developer Settings page. Store this token as an Actions secret under the name PUSH_TOKEN in the main repo (i.e. the repo where the docs source code is held). See more here.
