 * Class-level state (static fields, metaclass mutations) persists across evaluations

我們用 `list(data.items())` 把這個可疊代物件轉成正式的 `list`。

接著用 `random.choice()` 從清單中取得一個「隨機值」，也就是一個 `(id, name)` 的 tuple。可能像是 `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")`。

然後把這個 tuple 的兩個值分別指定給變數 `id` 和 `name`。

因此，即使使用者沒有提供 item ID，仍然會收到一個隨機建議。

……而這全部只用一行簡單的程式碼完成。🤯 你不愛 Python 嗎？🐍
