Registry
PyPI
The Python package index. A Taken result shows the summary, latest version and author; Names with -, _ or . get a PyPI normalization warning.
Each Check asks PyPI’s JSON API for the project. A 404 means Available.
PyPI normalization: PyPI treats -, _ and . as equivalent, so my-tool and my_tool are the same PyPI project. Any Name with one of those characters gets a warning with its results.
