This guide covers best practices for dependency management, virtual environments, and project configuration. ## uv - The Modern Package Manager ### Why uv? - **10-100x faster** than pip (written in Rust) - Replaces pip, pip-tools, pipx, poetry, pyenv, virtualenv - Automatic virtual environment management - Lockfile support for reproducibility - ~200x faster venv creation ### Installation ```bash # macOS/Linux curl -LsSf https://astral.sh/uv/install.sh | sh # Windows (PowerShell) irm https://astral.sh/uv/install.ps1 | iex # pip (works everywhere) pip install uv # Homebrew brew install uv ```
