Em seguida, com `random.choice()` podemos obter um valor aleatório da lista, então obtemos uma tupla com `(id, name)`. Será algo como `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")`.

Depois atribuímos esses dois valores da tupla às variáveis `id` e `name`.

Assim, se o usuário não fornecer um ID de item, ele ainda receberá uma sugestão aleatória.

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？🐍

Primero, echemos un vistazo rápido a las partes que cambian desde los ejemplos en el **Tutorial - User Guide** principal para [OAuth2 con Password (y hashing), Bearer con tokens JWT](../../tutorial/security/oauth2-jwt.md). Ahora usando scopes de OAuth2:

Ardından `random.choice()` ile list’ten **rastgele bir değer** alırız; yani `(id, name)` içeren bir tuple elde ederiz. Şuna benzer: `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")`.

Sonra tuple içindeki bu **iki değeri** `id` ve `name` değişkenlerine **atarız**.

Böylece kullanıcı bir item ID’si vermemiş olsa bile yine de rastgele bir öneri alır.
