Você pode usar as mesmas funcionalidades e ferramentas de validação que usa em modelos do Pydantic, como diferentes tipos de dados e validações adicionais com `Field()`.

### `Settings` 객체 만들기 { #create-the-settings-object }

Pydantic에서 `BaseSettings`를 import하고, Pydantic 모델과 매우 비슷하게 서브클래스를 만드세요.

Pydantic 모델과 같은 방식으로, 타입 어노테이션(그리고 필요하다면 기본값)과 함께 클래스 속성을 선언합니다.

다양한 데이터 타입, `Field()`로 추가 검증 등 Pydantic 모델에서 사용하는 동일한 검증 기능과 도구를 모두 사용할 수 있습니다.

### 建立 `Settings` 物件 { #create-the-settings-object }

從 Pydantic 匯入 `BaseSettings` 並建立子類別，與建立 Pydantic model 的方式非常類似。

就像使用 Pydantic model 一樣，你用型別註解宣告類別屬性，並可選擇性地提供預設值。

你可以使用與 Pydantic model 相同的所有驗證功能與工具，例如不同的資料型別與透過 `Field()` 進行額外驗證。
