Palm Python

Python on Palm: There is a port of PythonLanguage version 1.5.2 to the PalmOs in alpha stage at http://www.isr.uci.edu/projects/sensos/python/.
Python on Palm (Part 2): There is a port of PythonLanguage version 1.5.2 to the PalmOs called PipPy (which appears to be a continuation of the previous bullet item)
StacklessPython: Another port might come out of StacklessPython. At least there's a hint in that direction on http://www.tismer.com/research/stackless/.
Python on WinCe: Apparently there is some progress towards Python on WinCe (http://www.murkworks.com/Research/Python/PocketPCPython/Overview).
Python on small/embedded machines: there is a project about downsizing Python for small/embedded machines at http://www.abo.fi/~iporres/python/ (Broken as of 23-07-2003)
Python Modules for Synchronization: The PythonLanguage package Pyrite (which used to be called "PalmPython") is actually a set of Python modules to synchronize data with PalmOs machines, not an implementation of Python on handhelds. Homepage at: http://www.pyrite.org/
Python on Sharp Zaurus/Linux: Python runs just fine on Linux on the Sharp Zaurus. http://www.myzaurus.com/
