Modern Python Workflows with uv

Introduction

Chapter 03 introduces uv, Astral's Rust-based Python project and package manager, first released in 2024. Its project configuration centers on pyproject.toml, which records project metadata and dependencies, while its lockfile supports reproducible installs. The chapter covers scaffolding workspaces, building and publishing packages, managing and caching dependencies, using the cache in CI, and workflows for standalone scripts, environments, and command-line tools with uvx or uv pip.
