I'm not particulary worried about the version of Python. I grok Python fairly well. What I'm looking for are definitions of the Poser classes,  methods, etc., and that's been a real bitch to find. However, for anyone else looking for similar information, I did find this site useful: https://vdocuments.mx/poser-python-methods-manual.html?page=1. Not perfect, but it is possible to dig out the needed information.
