For example, you could add a custom header `X-Process-Time` containing the time in seconds that it took to process the request and generate a response:

{* ../../docs_src/middleware/tutorial001.py hl[10,12:13] *}

/// tip

For example, you could have a file `config.py` with:

{* ../../docs_src/settings/app01/config.py *}

And then use it in a file `main.py`:

{* ../../docs_src/settings/app01/main.py hl[3,11:13] *}

/// tip

You would also need a file `__init__.py` as you saw in [Bigger Applications - Multiple Files](../tutorial/bigger-applications.md){.internal-link target=_blank}.

您可以使用该技术在路径操作中重用一些预定义的响应，并将它们与其他自定义响应相结合。
**例如：**

## 有关OpenAPI响应的更多信息

要了解您可以在响应中包含哪些内容，您可以查看OpenAPI规范中的以下部分：
	+ [OpenAPI响应对象](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#responsesObject)，它包括 Response Object 。

### Классы как типы

Вы также можете объявить класс как тип переменной.

Допустим, у вас есть класс `Person` с полем `name`:

{* ../../docs_src/python_types/tutorial010.py hl[1:3] *}


Тогда вы можете объявить переменную типа `Person`:

{* ../../docs_src/python_types/tutorial010.py hl[6] *}
