Con esta declaración tu editor puede proveerte soporte inclusive mientras está procesando ítems de la lista.

Sin tipos el auto-completado en este tipo de estructura es casi imposible de lograr:

<img src="https://fastapi.tiangolo.com/img/python-types/image05.png">

Observa que la variable `item` es unos de los elementos en la lista `items`.

El editor aún sabe que es un `str` y provee soporte para ello.

And it generates OpenAPI schemas.

That's how it works in Flask, Starlette, Responder, etc.

But then, we have again the problem of having a micro-syntax, inside of a Python string (a big YAML).

The editor can't help much with that. And if we modify parameters or Marshmallow schemas and forget to also modify that YAML docstring, the generated schema would be obsolete.

# Debugging

You can connect the debugger in your editor, for example with Visual Studio Code or PyCharm.

## Call `uvicorn`

In your FastAPI application, import and run `uvicorn` directly:

```Python hl_lines="1  15"
{!../../../docs_src/debugging/tutorial001.py!}
```

### About `__name__ == "__main__"`

The main purpose of the `__name__ == "__main__"` is to have some code that is executed when your file is called with:

在这里，你的编辑器可能会这样帮助你：

* <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> 中:

你将能进行代码补全，这是在之前你可能曾认为不可能的事。例如，在来自请求 JSON 体（可能是嵌套的）中的键 `price`。

```Python
        ... "item_name": item.name ...
```

...a:

```Python
        ... "item_price": item.price ...
```

... y mira como el editor va a auto-completar los atributos y sabrá sus tipos:

...from:

```Python
        ... "item_name": item.name ...
```

...to:

```Python
        ... "item_price": item.price ...
```

...and see how your editor will auto-complete the attributes and know their types:

Up to now, you have been using common data types, like:

* `int`
* `float`
* `str`
* `bool`

But you can also use more complex data types.

And you will still have the same features as seen up to now:

* Great editor support.
* Data conversion from incoming requests.
* Data conversion for response data.
* Data validation.
* Automatic annotation and documentation.

## Other data types

    * **Hızlı**: **NodeJS** ve **Go** ile eşit, çok yüksek performans (Starlette ve Pydantic'e teşekkürler).
    * **Sezgisel**: Editor desteğı. <abbr title="auto-complete, IntelliSense gibi isimlerle de bilinir">Otomatik tamamlama</abbr>. Daha az debugging.
    * **Kolay**: Kolay öğrenip kolay kullanmak için tasarlandı. Daha az döküman okuma daha çok iş.
