How to version Python packages with uv

uv makes Python package management incredibly fast. Here's a quick pattern for managing dependencies:

# Initialize a new project
uv init my-project
cd my-project

# Add dependencies
uv add requests pandas

# Add dev dependencies
uv add --dev pytest ruff

# Run scripts
uv run python my_script.py

# Run tests
uv run pytest

The key insight: uv replaces pip, venv, pip-tools, and pyenv in a single tool. No more juggling multiple package managers.
