Python For Maemo 5 Info
The python used in the Nokia N900 is known as PyMaemo. It is basically the normal python, with additional device related commands.
API Documentation (non-pythonic): Maemo 5 Api Docs
Python Tutorials: Python for newbies
It is also possible to access C APIs that don't have Python bindings. However, this can bring some interesting problems. Not recommended, as most of the maemo APIs should work just fine with Python. However, check Accessing APIs without Python bindings for more info.
