這在你想接收尚未預知的鍵時很有用。

---

另一個實用情境是當你希望鍵是其他型別（例如，`int`）時。

這正是我們在此要示範的。

在此情況下，只要是擁有 `int` 鍵且對應 `float` 值的 `dict` 都會被接受：

{* ../../docs_src/body_nested_models/tutorial009_py310.py hl[7] *}

/// tip

請記住，JSON 只支援 `str` 作為鍵。

但 Pydantic 具有自動資料轉換。

這表示即使你的 API 用戶端只能以字串作為鍵，只要這些字串是純整數，Pydantic 會自動轉換並驗證它們。

而你作為 `weights` 所接收的 `dict`，實際上會擁有 `int` 鍵與 `float` 值。
