この反復可能オブジェクトを `list(data.items())` で適切な `list` に変換します。

そして `random.choice()` でその `list` から **ランダムな値** を取得するので、`(id, name)` のタプルを得ます。これは `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")` のようになります。

次に、そのタプルの **2つの値を代入** して、変数 `id` と `name` に入れます。

つまり、ユーザーが item ID を提供しなかった場合でも、ランダムな提案を受け取ります。

...これを **単一のシンプルな1行** で行っています。 🤯 Python が好きになりませんか？ 🐍

使用 `str | None` 而不是仅仅 `str`，可以让编辑器帮助你发现把值当成总是 `str` 的错误（实际上它也可能是 `None`）。

### 类作为类型 { #classes-as-types }

你也可以把类声明为变量的类型。

假设你有一个名为 `Person` 的类，带有 name：

{* ../../docs_src/python_types/tutorial010_py310.py hl[1:3] *}

然后你可以声明一个变量是 `Person` 类型：

{* ../../docs_src/python_types/tutorial010_py310.py hl[6] *}

接着，你会再次获得所有的编辑器支持：
