uv

uv is the Python tool manager preferred in Brevvie Python + AI — Section 1: Setup Your IDE. The lesson presents it as a modern replacement for older multi-tool workflows involving pyenv, venv, pip, and related tooling.

Role in the source

• Installs Python interpreters: uv python install 3.12
• Creates project environments: uv venv
• Installs packages: uv pip install ...
• Freezes dependencies: uv pip freeze > requirements.txt

Why it matters

The source treats uv as the clean default for avoiding system-Python problems and for standardizing environment setup across projects.
