Open Source Python Interpreters

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

Elmer is a tool which embeds a Python module into a C, C++, or Tcl application. The embedded Python module is used just as if it was written in the same language as the application itself, without requiring any knowledge of the Python/C API.

Pure Python implementation of GOLD Parser Engine. GOLD Parser Engine is a LALR(1) parser with DFA tokenizer. It uses compiled grammar table generated by GOLD Parser Builder (not included - available on http://www.devincook.com/goldparser)

An open source implementation of OpenAI's ChatGPT Code interpreter. Simply ask the OpenAI model to do something and it will generate & execute the code for you. You can put a .env in the working directory to load the OPENAI_API_KEY environment variable. For Azure OpenAI Services, there are also other configurable variables like deployment name. See .env.azure-example for more information. Note that model selection on the UI is currently not supported for Azure OpenAI Services.

Logix is a programming language where the syntax can be easily modified.

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.

The Snake Skin Bean Breaker converts Python syntax into readable Java syntax. With a high potential of runtime or compile-time deviances, the resultant code is assumed to be broken.. Works well for porting Jython Swing prototypes.

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

mySAL -- A simple single assignment language Single assignment languages are a kind of "functional" language where the parallelism is easy to discover. mySAL is a relative of SISAL, and old and distinguished SAL. The provided compiler and runtime

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.
