/// note | Nota

FastAPI sabrá que el valor de `q` no es requerido por el valor por defecto `= None`.

Tener `str | None` permitirá que tu editor te dé un mejor soporte y detecte errores.

///

## Validaciones adicionales { #additional-validation }

Vamos a hacer que, aunque `q` sea opcional, siempre que se proporcione, **su longitud no exceda los 50 caracteres**.

```

</div>

It is **HIGHLY encouraged** that you write or copy the code, edit it and run it locally.

Using it in your editor is what really shows you the benefits of FastAPI, seeing how little code you have to write, all the type checks, autocompletion, etc.

## Install FastAPI { #install-fastapi }

The first step is to install FastAPI.

<div class="termy">

```console
$ python main.py

Hello World
```

</div>

## Ihren Editor konfigurieren { #configure-your-editor }

{* ../../docs_src/response_status_code/tutorial002_py39.py hl[1,6] *}

Son solo una conveniencia, mantienen el mismo número, pero de esa manera puedes usar el autocompletado del editor para encontrarlos:

/// note | Detalles técnicos

También podrías usar `from starlette import status`.

But when you declare them with Python types (in the example above, as `int`), they are converted to that type and validated against it.

All the same process that applied for path parameters also applies for query parameters:

* Editor support (obviously)
* Data <abbr title="converting the string that comes from an HTTP request into Python data">"parsing"</abbr>
* Data validation
* Automatic documentation

## Defaults { #defaults }

{* ../../docs_src/response_status_code/tutorial002_py39.py hl[1,6] *}

Eles são apenas uma conveniência, eles possuem o mesmo número, mas dessa forma você pode usar o preenchimento automático do editor para encontrá-los:

<img src="/img/tutorial/response-status-code/image02.png">

/// note | Detalhes Técnicos

Você também pode usar `from starlette import status`.

```

</div>

Es wird **dringend empfohlen**, den Code zu schreiben oder zu kopieren, ihn zu bearbeiten und lokal auszuführen.

Die Verwendung in Ihrem eigenen Editor zeigt Ihnen die Vorteile von FastAPI am besten, wenn Sie sehen, wie wenig Code Sie schreiben müssen, all die Typprüfungen, die automatische Vervollständigung usw.
