As far as I know, there was no tool yet to convert metadata associated with Python packages (pip/pypi/distutils) to codemeta. I therefore started to work on this, analogous to what codemetar does for R, and have a first prototype available: https://github.com/proycon/codemetapy . It is designed to parse pip show -v output but has various extra abilities as well. I hope it may prove a valuable addition to this interesting project.
