Open Source Python Interpreters

PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, AIX and Solaris. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.3, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. You'll never be required to look for tricks in wikis and apply custom modification to your files or your setup scripts. As an example, libraries like PyQt, Django or matplotlib are fully supported, without having to handle plugins or external data files manually.

Psyco showed that it is possible to execute Python code at speeds approaching that of fully compiled languages, by "specialization". The project is now dead and replaced by PyPy: http://pypy.org/

GDL - GNU Data Language, a free IDL (Interactive Data Language, see http://ittvis.com/idl/) compatible incremental compiler.

Broccoli is a dynamically-typed, multi-paradigm programming language.

The Esoteric Project is a project devoted to providing interpreters and/or compilers for every Turing-complete Esoteric Programming Language.

LucidEngine is a simple layer over MIDP compatible phones that will let you write simple and old fashioned games using a specific language. Every game you'll develop will basically work on all the devices (even not phones) LucidEngine as been ported.

Build windows executable from your Python file, with areas that requires your program info, description, Icon etc. It is possible to load existing data sets, given they are under corresponding Pickle formats, while saving also generates an Pickle file. Info fields can meet most demands, Windowed or consoled program type. One-file or Folder package, Encryption module, Hidden-Imports, UPX Compatible, Icon, program end-name, Debug mode and more.

The Markovski project implements an interpreter/compiler for a language named Markovski, used to write Markov algorithms (see http://en.wikipedia.org/wiki/Markov_algorithm).

Multi-language library to deal with multimethod dispatch, disambiguation and type-checking using dispatch tables. This approach yields fast dispatch in constant-time and greatly helps resolving ambiguities.

PLT Spy is a Python to Scheme translator.

Pygone is to be a programming language built on top of Python, aimed to be a ridiculously high level programming language, allowing for it to be used to introduce people to programming.

Collection of Python for Windows that can be installed anywhere (hard drive, usb key, network..). No external dependencies and no side effect. 2 configurations: minimal and complete, with additional packages. For python 16, 20 to 27 and 32

Waxeye is a parser generator based on parsing expression grammars (PEGs). It supports C, Java, Javascript, Python, Ruby and Scheme.

It's a brainfuck interpreter written in Python (In the future will be also a compiler for x86 and have a GUI).
