brython VS jupyterlite

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.

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

The JupyterLite Python-compiled-to-WASM build has NumPy, SciPy, matplotlib, and SymPy installed; so you can do computer algebra with SymPy in a browser tab.

Agreed that would be a killer feature. Unzip this package and get a functional Python + Jupyter + scientific (numpy, pandas, scipy, matplotlib) environment.

I have been on-and-off teaching some people Python and the initial setup on-ramp is horrible. Ok, so install Python, now ignore-this-for-now-complications: create a "virtualenv", use this thing called "pip", install these half-dozen things to get a basic notebook (Jupyter + scipy things), install these other half-dozen quality of life things, you should probably also have "conda" for the future, etc. That's a lot of nonsense for someone I am trying to show an alternative to Excel.

My shortcut, "You want to try Python?" approach has been to start with JupyterLite[0] where I can immediately get people coding and delay that pain.
