Python Implementations
An "implementation" of Python should be taken to mean a program or environment which provides support for the execution of programs written in the Python language, or some broadly similar dialect of the language.
There have been and are several distinct software packages providing of what we all recognize as Python, although some of those are more like distributions or variants of some existing implementation than a completely new implementation of the language.
CPython Variants
CPython - the reference Python implementation
ActivePython - a CPython variant
Other Implementations
CLPython - Python in Common Lisp
IronPython - Python in C# for the Common Language Runtime (CLR/.NET)
Jython - Python in Java for the Java platform
PyMite - Python for embedded devices
PyPy - Python in Python, targeting several environments
tinypy - a minimalist implementation of python in 64k of code
Closely related but arguably distinct languages
- Boo
Compilers
Compyler - an attempt to "transliterate the bytecode into x86 assembly"
Shed Skin - a Python-to-C++ compiler
