WebAssembly: Adding Python Support to WASM Language Runtimes
9 projects | news.ycombinator.com | 31 Jan 2023

I have been following and playing with this repository: https://github.com/singlestore-labs/python-wasi/
It builds a single Python WASM module with all dependencies included (they use VFS) and a Dockerfile to make the process easy (and actually worked first go). It does produce large files though: wasi-python3.11.wasm 110MB

WebAssembly: Adding Python Support to WASM Language Runtimes
9 projects | news.ycombinator.com | 31 Jan 2023

I've not yet figured out the incantations I need to actually do this - in particular the limits on CPU and memory time.
I posed this question on Mastodon recently and Jim Kring put together this demo, which gets most of the way there (albeit using an old Python 3.6 build): https://github.com/jimkring/python-sandbox-wasm
It doesn't feel like this should be as hard to figure out as it is!
