Python packaging with pyproject.toml streamlines project configuration by replacing setup.py with a declarative standard. It manages build backends, dependencies, and metadata in one file, ensuring reproducible builds and consistent project setups.

The best way to manage Python package versioning and publishing is by integrating versioning strategies and build backend configurations within pyproject.toml. This standardizes releases and enables effortless publishing workflows to PyPI.

Yes, this packaging approach works with both hatchling and setuptools build backends. The guidance provides specific configuration examples to standardize builds regardless of which modern backend you choose for your project.

Configuring dependencies and testing in a modern Python package requires defining them within your pyproject.toml file. This centralizes your project requirements and integrates testing workflows directly into your build and release process.

You need to adopt a src layout for Python packaging when you want to enforce strict separation between your package code and other project files. This structure prevents local import errors and improves testing reliability.
