Use Semantic Versioning (SemVer) to manage versioning. Increment version numbers based on changes, and utilize tools like `setuptools` and `twine` for packaging and distribution.

Managing versioning in Python packages is essential for maintaining compatibility and ensuring users can track changes effectively. A widely adopted approach is Semantic Versioning (SemVer), which uses a three-part version number: MAJOR.MINOR.PATCH. Increment the MAJOR version for incompatible changes, the MINOR version for backward-compatible features, and the PATCH version for backward-compatible bug fixes. This clear versioning scheme helps users understand the nature of changes and compatibility. When releasing your package, utilize tools like setuptools to define package metadata and manage dependencies. After packaging, use twine to securely upload your package to repositories like PyPI. It’s also a good practice to include a changelog in your project to document changes and improvements in each version. Consider leveraging continuous integration (CI) tools to automate versioning and packaging, ensuring that new releases are handled consistently. By following these practices, you can effectively manage versioning in your Python packages.
