You can implement a Python package using Poetry, which simplifies the packaging process by covering dependency management, packaging, and publishing. To get started with Poetry, you'll need Python 3.8+ and Poetry 1.4.2. Create a new project with `poetry init`, add dependencies, create a virtual environment, and install the package using `poetry install`. You can then add code to your package, including a CLI interface, tests, and publishing to PyPI. To automate this process, you can use GitHub Actions to run tests, publish releases, and deploy your package.
