Unfragile

The request names packageurl-python, a Python library for Package URL (purl) parsing and building, but none of the candidate sources describes that library directly. The closest matches are general Python packaging tools: PyPA's packaging documentation 2, which covers the PyPI packaging ecosystem, and Hynek Schlawack's build-and-inspect action 10, which builds and checks Python packages. Neither source confirms purl handling, so the list is only a loose fit.

A question back: Do you want the packageurl-python library itself (its PyPI page or repository), or a general Python packaging tool to help build and publish a package?
