If you need a “real” python envoriment, you will need to call python.exe your self using Start Process and then map any data you need in/out in some other way, like a local json file.
OR wait a few days to version 1.5 of openflow to be released, then you can run real python inside openflow
This also allows using the “opeiap” py liberary to be installed so you can talk directly to openflow from python.
