* `summary`: Örnek için kısa açıklama.
* `description`: Markdown metni içerebilen uzun açıklama.
* `value`: Gösterilecek gerçek örnek (ör. bir `dict`).
* `externalValue`: `value`’a alternatif; örneğe işaret eden bir URL. Ancak bu, `value` kadar çok araç tarafından desteklenmiyor olabilir.

Şöyle kullanabilirsiniz:

{* ../../docs_src/schema_extra_example/tutorial005_an_py310.py hl[23:49] *}

* `summary` : une courte description de l'exemple.
* `description` : une description longue qui peut contenir du texte Markdown.
* `value` : c'est l'exemple réel affiché, par ex. un `dict`.
* `externalValue` : alternative à `value`, une URL pointant vers l'exemple. Cependant, cela pourrait ne pas être pris en charge par autant d'outils que `value`.

Vous pouvez l'utiliser ainsi :

    builder.setUnsafeReplacement("\uFFFD");

    /*
     * Except for \n, \t, and \r, all ASCII control characters are replaced with the Unicode
     * replacement character.
     *
     * Implementation note: An alternative to the following would be to make a map that simply
     * replaces the allowed ASCII whitespace characters with themselves and to set the minimum safe

* `app`: das Objekt, das innerhalb von `main.py` mit der Zeile `app = FastAPI()` erstellt wurde.

Es ist äquivalent zu:

```Python
from main import app
