Python is a general-purpose, very high-level, dynamically-typed, byte-code compiled, ObjectOriented language. It has a virtual machine available for most current operating systems. PikiePikie is written in Python.
Python's goal is to be simple and powerful enough, and it certainly shows in its clean syntax and yet, amazingly rich semantics. It comes loaded with a full featured library and many third-party OpenSource modules are available.
If you can't find a Python interpreter for your platform of choice, there's always Jython anyway...
