PDM

A Python package and dependency manager. PDM implements modern Python packaging standards like PEP 517/518 and uses PEP 621 metadata in pyproject.toml.

⚠️
While PDM is a capable tool, consider using uv instead for better performance, simpler workflows, and unified tooling across Python package/environment management.
