## Pydantic `Settings` { #pydantic-settings }

Afortunadamente, Pydantic proporciona una gran utilidad para manejar estas configuraciones provenientes de variables de entorno con [Pydantic: Settings management](https://docs.pydantic.dev/latest/concepts/pydantic_settings/).

### Instalar `pydantic-settings` { #install-pydantic-settings }

Il convertira ensuite et validera les données. Ainsi, lorsque vous utilisez cet objet `settings`, vous aurez des données des types que vous avez déclarés (par exemple, `items_per_user` sera un `int`).

### Utiliser `settings` { #use-the-settings }

Vous pouvez ensuite utiliser le nouvel objet `settings` dans votre application :

{* ../../docs_src/settings/tutorial001_py310.py hl[18:20] *}

### Exécuter le serveur { #run-the-server }

## Pydantic `Settings` { #pydantic-settings }

다행히 Pydantic은 환경 변수에서 오는 이러한 설정을 처리할 수 있는 훌륭한 유틸리티를 [Pydantic: Settings 관리](https://docs.pydantic.dev/latest/concepts/pydantic_settings/)로 제공합니다.

### `pydantic-settings` 설치하기 { #install-pydantic-settings }

먼저 [가상 환경](../virtual-environments.md)을 만들고 활성화한 다음, `pydantic-settings` 패키지를 설치하세요:

<div class="termy">

```console

///

接著，當你建立該 `Settings` 類別的實例（此處為 `settings` 物件）時，Pydantic 會以不區分大小寫的方式讀取環境變數，因此，即使環境變數是大寫的 `APP_NAME`，也會被讀入屬性 `app_name`。

然後它會轉換並驗證資料。因此，當你使用該 `settings` 物件時，你會得到你宣告的型別的資料（例如 `items_per_user` 會是 `int`）。

### 使用 `settings` { #use-the-settings }

接著你可以在應用程式中使用新的 `settings` 物件：

{* ../../docs_src/settings/tutorial001_py310.py hl[18:20] *}

### 執行伺服器 { #run-the-server }

接下來，你可以在啟動伺服器時，將設定以環境變數傳入。舉例來說，你可以設定 `ADMIN_EMAIL` 與 `APP_NAME`：
