We understand how important it is for Luna to be able to use Python (and JS) libraries and we will try to get to work on that asap. Please note, however, that the core Luna team is fairly small, so we have limited capacity (although I would like to make it my personal goal to create the Python ffi). That said, any community effort in this area is more than welcome, you can check the code on our github org: https://github.com/luna
