Keeping up with the Python ecosystem can be daunting. Its developer tooling doesn’t provide the out-of-the-box experience native to languages like Rust and Go. When it comes to long-term project maintenance or collaborating with others, every Python project faces the same problem: how to build reliable workflows beyond local development while staying in sync with the evolving ecosystem.

With this hands-on guide, Python developers will learn how to forge the moving parts of a Python project into an easy-to-use toolchain, using state-of-the-art tools including Poetry, Nox, pytest, mypy, pre-commit, Black, Ruff, uv, Rye, Hatch, and more. Author Claudio Jolowicz shows you how to create robust Python project structures complete with unit tests, static analysis, code formatting, and type checking.

You’ll learn how to:

• Create open source projects with state-of-the-art infrastructure
• Build a custom infrastructure for all Python projects in a company or team
• Improve and modernize the infrastructure of an existing Python project
• Evaluate modern Python tooling for adoption in existing projects
• Use tools for packaging and dependency management
• Automate common development tasks such as testing, dependency updates, and publishing releases
