A Python interpreter written in JavaScript (just plain JavaScript), that MUST conform perfectly to the Python 3.3.0 specifications for Cython (C Python). Pyjamas already exists. It is a Python to JavaScript translator. Because Pyjama translations are not accurate, I am making this project. Estimated final size: 200,000 to 300,000 lines of JavaScript (this is a BIG project). If you want to help, please just start coding and then talk to me. Everything is open source because of the Python Software Foundation.
