At http://www.monkeyhouse.eclipse.co.uk/mobile/python.htm you can find my independent attempt to port Python to Symbian OS devices. It is a new port from the generic Python 2.3.3 sources. The Python interpreter works in console mode, and most of the standard library modules work as expected. I am launching the project publicly now as I have completed the first proof of concept and am now inviting ideas and contributions. There is still lots of work to do. The software runs inside the emulator, but is of no use on a real device as there is no way to enter text (except possibly with an IR keyboard, but I haven't tried that). I have not seen the Nokia Series 60 runtime, but am aware of it. I don't know what their intentions are regarding open source licensing, but if their work is available on appropriate terms, then I would rather use that for this project than reinvent the wheel. Currently, the Python interpreter runs and you can interactively enter Python programs or code fragments. Please get in touch if you are interested in contributing.
