Python 3.11 in the Web Browser

• pyground

  2 16 0.0 TypeScript

  Playground for running Python using WASM on data in the browser

  Yep, it’s all static with no server side and the Python all runs locally. The source is on GitHub: https://github.com/mcintyre94/pyground so you can run it locally or deploy it yourself if you’d like too

• pyodide

  70 12,536 9.7 Python

  Pyodide is a Python distribution for the browser and Node.js based on WebAssembly

  

  Those interested in this should check out Pyodide[0]. It basically "just works" so long as the libraries you import are pure Python or are part of the core scientific stack (the Pyodide authors have done the work to manually port all the C code behind numpy, scipy, etc.).

  What I really wish for is for ~all Python packages to work in the browser without manual porting of the underlying C/Rust/etc. being needed, since a lot of the interesting and useful libraries aren't pure Python, and manual porting is non-trivial.

  I'm not sure what the best route to that future is, but I'm guessing it'd probably help if Python had a wasm runtime in its standard library[1], since then authors of libraries that use C/Rust/etc. might make cross-platform builds (perhaps by default).

  Regarding this Pycon speech, it seems that it's related to this entry in the 3.11 changelog[2], which the speaker was heavily involved with:

  > CPython now has experimental support for cross compiling to WebAssembly platform wasm32-emscripten. The effort is inspired by previous work like Pyodide. (Contributed by Christian Heimes and Ethan Smith in bpo-40280[3])

• skulpt

  1 7 2.7 JavaScript

  Skulpt is a Javascript implementation of the Python programming language (by blockpy-edu)

  

  MatPlotLib support in Skulpt for BlockPy [1]. Not complete, but workable for a lot of common graphs that I use in my CS1 course.

  Can someone explain to me, really slowly please, how to take an existing Python codebase such as https://github.com/infojunkie/mma and run it in the browser using one of the technologies mentioned in this thread? Especially, how to deal with filesystem calls that expect some files to be present in various folders. Thanks!
