Chapter 15: Python UV — The Fastest Python Package Manager
Before you write Python programs, you need professional tools for managing dependencies, virtual environments, and project structure. This beginner-friendly chapter teaches you UV, the fastest Python package manager (written in Rust), along with complementary tools Ruff (linter/formatter) and Pyright (type checker) that integrate seamlessly with UV.
You'll set up production-quality Python environments before writing your first print() statement—because modern Python development requires professional-grade project management from day one. This chapter focuses on tool installation and basic usage, not Python programming itself. You'll learn through simple AI-driven workflows where you specify what you want and AI helps with commands.
🎯 Before You Begin
What You'll Learn
By the end of this chapter, you will be able to:
- Explain what UV, Ruff, and Pyright are and why modern Python developers use them
- Understand why UV is faster than pip, pipenv, and poetry
- Recognize when to use direct commands vs. asking AI for help
- Describe what each tool does (package management, formatting, type checking)
- Install UV, Ruff, and Pyright on your computer (Windows, macOS, or Linux)
- Create and manage Python projects with UV
- Run basic formatting and linting commands with Ruff
- Check Python code for type errors using Pyright
- Configure simple project settings with AI assistance when needed
