Python ported to WebAssembly

Python

Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python's design philosophy emphasizes code readability with its notable use of significant whitespace.

You can install python with:

wapm install python

Original Source: https://github.com/iodide-project/pyodide

Modification: The original code (Pyodide) ported Python to the browser via WebAssembly. We made some adaptations to remove the JavaScript bindings and to expose the main function so it can be called as a CLI app.

Running

You can run the python shell:

$ wapm run python
Python 3.7.0 (default, Jun 12 2019, 21:15:06)
[Clang 6.0.1 ] on emscripten
Type "help", "copyright", "credits" or "license" for more information.
>>> this_is = "wapm"
>>> print(f"Hello from {this_is}")
Hello from wapm
>>>

Building from Source

You will need Emscripten SDK (emsdk) to build bin/python3.7.wasm file.

Steps:

1. Setup emsdk (>= 1.38.11), see Installation Instructions
2. Run bash build.sh
