Dikkatinizi çekerim ki, fonksiyonunuzun aldığı (ve döndürdüğü) değer olan `3` bir string `"3"` değil aksine bir Python `int`'idir.

Bu tanımlamayla birlikte, **FastAPI** size otomatik istek <abbr title="HTTP isteği ile birlikte gelen string'i Python verisine dönüştürme">"ayrıştırma"</abbr> özelliği sağlar.

/// check

Notice that the value your function received (and returned) is `3`, as a Python `int`, not a string `"3"`.

So, with that type declaration, **FastAPI** gives you automatic request <abbr title="converting the string that comes from an HTTP request into Python data">"parsing"</abbr>.

///

## Data validation

```JSON
{"item_id":3}
```

/// check | Revisa

Observa que el valor que recibió (y devolvió) tu función es `3`, como un Python `int`, y no un string `"3"`.

Entonces, con esa declaración de tipos **FastAPI** te da <abbr title="convertir el string que viene de un HTTP request a datos de Python">"parsing"</abbr> automático del request.

///

## Validación de datos

**Gunicorn** ist hauptsächlich ein Anwendungsserver, der den **WSGI-Standard** verwendet. Das bedeutet, dass Gunicorn Anwendungen wie Flask und Django ausliefern kann. Gunicorn selbst ist nicht mit **FastAPI** kompatibel, da FastAPI den neuesten **<a href="https://asgi.readthedocs.io/en/latest/" class="external-link" target="_blank">ASGI-Standard</a>** verwendet.

/// note

**FastAPI** saura que la valeur de `q` n'est pas requise grâce à la valeur par défaut `= None`.

Le `Union` dans `Union[str, None]` permettra à votre éditeur de vous offrir un meilleur support et de détecter les erreurs.
