# Essential Developer Tools for Python and AI Projects

> Master the professional tools every Python developer needs: Git for version control, environment variables for secrets, and modern package management.

Before you can build real Python projects — especially those involving AI and APIs — you need to be comfortable with the tools that professional developers use every day. These aren't optional extras: Git protects your work and enables collaboration, environment variables keep your secrets safe, and modern package managers like `uv` make dependency management dramatically faster and simpler. Think of this section as equipping your workshop before you start building.

## What you'll learn

Every Python developer needs these tools:

* **Git & GitHub** — Save your work, track every change, and collaborate with others
* **Environment variables** — Keep API keys and secrets safe and manage configuration
* **Code quality** — Automatically format and lint your code
* **Modern Python tools** — Better ways to manage packages and dependencies

These tools are especially important for AI development, where you'll share code, work with API keys, and manage complex dependencies.
