/// tip

如果您需要一个快速的复制粘贴示例，请不要使用此示例，而应使用下面的最后一个示例。

///

然后，当您创建该 `Settings` 类的实例（在此示例中是 `settings` 对象）时，Pydantic 将以不区分大小写的方式读取环境变量，因此，大写的变量 `APP_NAME` 仍将为属性 `app_name` 读取。

然后，它将转换和验证数据。因此，当您使用该 `settings` 对象时，您将获得您声明的类型的数据（例如 `items_per_user` 将为 `int` 类型）。

### 使用 `settings`

然后，您可以在应用程序中使用新的 `settings` 对象：

{* ../../docs_src/settings/app02_an_py39/config.py hl[10] *}

Обратите внимание, что теперь мы не создаем экземпляр по умолчанию `settings = Settings()`.

### Основной файл приложения { #the-main-app-file }

Теперь мы создаем зависимость, которая возвращает новый `config.Settings()`.

{* ../../docs_src/settings/app02_an_py39/main.py hl[6,12:13] *}
