A collection of self-contained Python snippets, examples, and small utilities.
Each snippet lives in its own directory with a pyproject.toml describing its
dependencies. The recommended way to run any snippet is with
uv:
# Run a snippet directly (uv handles the virtual environment and dependencies)
cd snippet_directory
uv run python script_name.py
# Or create a virtual environment first
cd snippet_directory
uv sync
uv run python script_name.pyIf you don't have uv installed:
# Install uv (macOS / Linux)
curl -LsSf https://astral.sh/uv/install.sh | sh
# Install uv (Windows)
