Quote from tehpola and comex:

PyOGC is an OGC wrapper for Python written in Pyrex (a hybrid Python-C language designed for extension development). The author, tehpola, made a working demo, but the demo itself was made in Pyrex, not real Python. I (comex) hacked Python a little so the interpreter as well would run, and you can run .py files.

Aside from Python being an awesome language, I think Python on Wii might eventually make it much easier for GUI applications to be developed on the Wii, or really anything.

Right now, however, it does not have any GUI, and PyOGC itself is incomplete– this is really just a demo. The finished version might have have a file selector and maybe a GUI and all that fancy stuff.
