package path followed by a period and the symbol name:
<code>fmt.Printf</code> or <code>math/rand.Int</code>.
Because the assembler's parser treats period and slash as punctuation,
those strings cannot be used directly as identifier names.
Instead, the assembler allows the middle dot character U+00B7
and the division slash U+2215 in identifiers and rewrites them to
plain period and slash.

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()`.

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

Glücklicherweise bietet Pydantic ein großartiges Werkzeug zur Verarbeitung dieser Einstellungen, die von Umgebungsvariablen stammen, mit <a href="https://docs.pydantic.dev/latest/concepts/pydantic_settings/" class="external-link" target="_blank">Pydantic: Settings Management</a>.

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

{* ../../docs_src/settings/tutorial001.py hl[2,5:8,11] *}

/// 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：
