here is an alpha version: pya7_alpha.exe ~14mb
i have quickly converted knights on wheels to python as an example but it's all still a bit unpolished.

it's compiled for python 2.6 and you need the engine version 7.77 or later. you have to edit the bat files and use them to create a dll which is bound to python.exe or pythonw.exe (depending on what you or your IDE use).
