Fix Python Tutorial

language-support/building-a-simple-component/python.html の「Running components from Python Applications」セクションから始め、現在のパッケージを使って、記載されている wasmtime.bindgen コマンドを再現してください。参照されている wasmtime-py の issue #309 と #310 を読んでサポート状況を確認し、そのうえで、検証済みのワークフローまたは利用可能性についての明確な注記をチュートリアルに追加し、例がユーザーを誤解させなくなったことを確認してください。

Hello,

I encountered an issue while following the "Running components from Python Applications" section in the documentation.

The documentation currently instructs users to install wasmtime and then run:
python3 -m wasmtime.bindgen add.wasm --out-dir add
However, with the current wasmtime package, this fails with:
No module named wasmtime.bindgen

It looks like wasmtime.bindgen was removed from wasmtime-py in bytecodealliance/wasmtime-py#310. The PR says that wasmtime.bindgen was removed in favor of component support in the C API, and that reimplementing bindgen for components is deferred to future work in bytecodealliance/wasmtime-py#309.

So I think this section of the documentation may now be outdated.

Expected behavior

The tutorial should provide a working way to run the add.wasm component from a Python host application, or mention that this workflow is no longer available with current versions of wasmtime-py.

Actual behavior

The documented command fails because wasmtime.bindgen is no longer available.

Environment

• Python 3.12.3 via pyenv
• wasmtime: latest version installed by pip install wasmtime
• OS: Ubuntu 24.04.1 LTS (Noble Numbat)
• Architecture: x86_64
