**FastAPI** is not actually an alternative to **Requests**. Their scope is very different.

It would actually be common to use Requests *inside* of a FastAPI application.

!!! info

!!! note "Технические детали"
    `FastAPI` это класс, который наследуется непосредственно от `Starlette`.

    Вы можете использовать всю функциональность <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> в `FastAPI`.

### Шаг 2: создайте экземпляр `FastAPI`

```Python hl_lines="3"
{!../../../docs_src/first_steps/tutorial001.py!}
```

同样，您将能够在与**FastAPI**无关的代码的其他部分中使用相同的 SQLAlchemy 模型和实用程序。

例如，在具有[Celery](https://docs.celeryq.dev/)、[RQ](https://python-rq.org/)或[ARQ](https://arq-docs.helpmanual.io/)的后台任务工作者中。

## 审查所有文件

最后回顾整个案例，您应该有一个名为的目录`my_super_project`，其中包含一个名为`sql_app`。

`sql_app`中应该有以下文件：

* `sql_app/__init__.py`：这是一个空文件。

* `sql_app/database.py`：

```Python

    Sie können alle <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a>-Funktionalitäten auch mit `FastAPI` nutzen.
