pyodide VS brython

Thank you! Yes, one of the items in the Roadmap is support for Pyodide (https://github.com/pyodide/pyodide) for running in-browser python on the results of each of the code blocks! This should allow most ML libs to be usable in-browser! This is pretty high-up on our priority list.

If I understand correctly, WASM only makes sense for compiled languages, you can run the python interpreter in WASM of course[1], but that will be at a significant performance disadvantage to the native javascript interpreter, and it's also something that has to be loaded every time you load the website.

If you absolutely need something comparable to Sympy, then one option might be to figure out how to best call Sympy from Rust. e.g. - RustPython, although it seems like Sympy isn't supported yet - Pyodide, and figuring out how to run it outside of a web browser. Probably also not very easy. - PyPy, and having a pretty simple Python binary for every platform - ...

For running programming languages other than JavaScript in the browser there is Emscripten and WebAssembly. There is v86, where a Linux build is compiled to WASM. Folks have written QuickJS into a Linux build compiled to WASM, Node.js into the Linux buildroot https://github.com/cemalgnlts/now, so Python or CPython can be written to the image and loaded into the browser as WASM as well https://github.com/pyodide/pyodide.

There's a Python runtime that runs on WebAssembly (https://github.com/pyodide/pyodide). I have no idea what it's like, I've never used it.

Still in a quest to provide some tooling to quickly compose documentation websites: https://github.com/synw/docdundee . As I have tons of libs to document and was tired of managing restructured language for readthedocs I started with this, and now it has executable Python examples in the frontend via a Pyodide wrapper composable: usePython

This project's brand new and a lil hacky, but I've already reached out to the scikit-learn team, and they recommended that I experiment with using Pyodide as an alternative backend for the Python bridge.

You can use my package usePython or directly Pyodide to run Python code in the browser with the ability to use Numpy and Pandas as well as any other pip package. Note that the former comes with a Vuejs code editor Vuepython

Or through an interpreter: https://github.com/brython-dev/brython

I'm a bit sceptical. It's actually not the first time someone wants to include Python in the browser, for example, brython has tried something similar.

This uses Pyodide [0] under the hood [1], which is CPython compiled to WebAssembly. In all my tests of it, loading takes a long time ~5 seconds. Coldbrew [2], another distribution of CPython on Wasm, is another option with similar load times.

And Brython [3] is a completely different option without long load time: a Python interpreter implemented in JavaScript.

If load time is important, Brython is pretty nice. If feature completeness is important, Pyodide and Coldbrew are probably best.

Brython python implementation that runs in the browser

Yes you can use a tool such as brython. But i think you should learn javascript of you want to be a web developer.
