I think Pyodide is what you want.

#6This is awesome. Thanks for doing this.
Took me a while to understand that exports are available for the wasm module to call and imports are what the wasm module can see to call.

The webassembly-language-runtimes is focused on providing WASI-based language interpreters, what would require a WASI polyfill at the browser level (https://wasi.dev/polyfill/) and (https://github.com/bjorn3/browser_wasi_shim).
Pyodide is certainly another option, but is emscripten based, not based in webassembly-language-runtimes or WASI.

#8This is exciting! Does that mean that I can load a sqllite db or a duckdb onto the browser through wasm and then connect it with the python env?

It's not quite as open as the language of your choice. There are a handful of popular languages available, Rust, C, C++ and a number of fringe languages like Zig, AssemblyScript, etc. You can run something like Python but it's a bit misleading because you're compiling the entire runtime to WebAssembly similar to how CheerpJ runs Java or Blazor runs .NET

The Python builds from the WebAssembly language runtimes [0] project target the WebAssembly System Interfaces (WASI) [1]. It allows the Python interpreter to interact with resources like the filesystem.
Many server-side Wasm runtimes supports WASI out of the box. For the browser, you need to provide a polyfill to emulate these resources like the one provided by the WASI team [2].
Regarding SQLite, these builds include libsqlite so you should be able to use it :)
