I came across this example: https://til.simonwillison.net/webassembly/python-in-a-wasm-sandbox which only shows how to get the result as an output at the end of Python execution.
Is it possible to have the sandboxed script call external Python functions provided by wasmtime?

This would be more of a question for https://github.com/vmware-labs/webassembly-language-runtimes

Another example you might be interested in is https://github.com/bytecodealliance/wasmtime-py/ for a Wasmtime embedding in Python. Otherwise though it looks like this is answered, so I'm going to close. Happy to follow-up if needed, however.

And you might also want to take a look at bytecodealliance/componentize-py, which is a much more fully-featured Python embedding in wasm.
