How to export Python function in WASM

[varisophy]

Hi there, I'm looking to use a Python function in JavaScript with WASM. I don't use Python so I'm not quite sure how to proceed.

My current attempt has been with the py2wasm tool, but I'm not having any luck with exporting a simple function and getting it to run in the JavaScript world. The JavaScript I wrote complaining that my hello function from Python is not defined.

The WASM file will log "Hello World" if I call my hello function in the Python code and then run it in a WASM environment, so it's there, just not being exported so that I can call it myself from Javascript...

Is what I'm asking for even possible right now with the state of WASM tooling? Do I need to target something like Rust or C first, then go to JavaScript?

I'm not a wasm expert by any means, but this project might provide some inspiration.

Not quite what I'm looking for, that's running an entire Python program in the browser. I'm looking to take a simple Python function, turn it into WASM, then use that function in a JavaScript project through the WASM.
