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.

A collection of extensions for Python's IDLE, the Python IDE built with the tkinter GUI toolkit.

Python port for Windows CE (Pocket PC) devices. Intended to be as close to desktop version as possible (console, current directory support, testsuite passed).

Jython is a Java implementation of the Python language. It allows users to compile Python source code to Java byte codes, and run the resulting bytecodes on any Java Virtual Machine. It is the successor to JPython.

PC-BASIC is a free, cross-platform interpreter for GW-BASIC, BASICA, PCjr Cartridge Basic and Tandy 1000 GWBASIC. -- This page is an archive and hosts the legacy version 1.2 of PC-BASIC only. -- For documentation and the latest releases, please see the official homepage: www.pc-basic.org Four source code, discussions and to report bugs please see the GitHub project page https://github.com/robhagemans/pcbasic

The Python programming language for S60 mobile phones.

JPype is an effort to allow python programs full access to java class libraries. This is achieved not through re-implementing Python, as Jython/JPython has done, but rather through interfacing at the native level in both Virtual Machines. Maintenance and evolution of the project has moved! please see http://www.jpype.org for the latest version

ACDK - Artefaktur Component Development Kit - is a platform independent C++-framework similar to Java or C#/.NET for generating distributed and scriptable components and applications.

Pyexpander is a powerful macro processor based on python. Instead of simple macro replacement it offers evaluation of arbitrary python expressions and execution of python code. Pyexpander is Turing Complete.

The Python programming language, an object-oriented scripting and rapid application development language. You can download it from http://www.python.org/download

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/

GUESS, or the Graph Exploration System, is a system and language for visualizing and manipulating graph structures and creating new visualization applications.

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

Provides a Python interpreter binding for Ada 95 programs.

A Python interface to the GSL library. The wrapper covers nearly everything GSL provides.

That project aims at providing a clean API, and the corresponding C++ implementation, for parsing travel-focused requests (e.g., "washington dc beijing monday r/t +aa -ua 1 week 2 adults 1 dog").

The focus of this project is to port the OO interpreter language Python and its extensions (GUI, CORBA, SOAP, XML-RPC, QNX message passing, Data Bases a.s.o) to QNX4 and QNX6 (QNX RTP). URLs: www.python.org

A Python extension for the SQLite Embedded Relational Database.

FramerD is a distributed semi-structured object database originally developed at MIT. It provides an internationalized Scheme-based scripting language, built-in text analysis tools, and special support for web scripting.

A library which provides the same functionality as the Python/C API detailed at python.org, thus allowing objective caml programmers to provide python modules as native ocaml code, as well as allowing ocaml code to use python extensions.

A server-side language that supports simple and efficient Python-based dynamic HTML generation, aka Python Server Pages. Those familiar with JSP, PHP, or ASP and like Python, should have a look at Spyce.

SilenceVST is an extensible, open-source language for programming music and sound on Windows. SilenceVST consists of a set of Python extensions and a custom Python shell that runs either standalone, or as a VST plugin.

Embed Prolog directly in your Python, C# or Javascript program using the yield keyword. There is no API standing between your code and Yield Prolog, so you can use all language features, including arrays, file I/O, user interaction and your own classes.

ChinesePython is a translation of Python scripting language itself into chinese. Not only the variable names, user messages/warnings/prompts but most notably, the reserved keywords and builtin types.
