```Python
some_variable: PlaneItem | CarItem
```

Aber wenn wir das in der Zuweisung `response_model=PlaneItem | CarItem` machen, würden wir einen Fehler erhalten, weil Python versuchen würde, eine **ungültige Operation** zwischen `PlaneItem` und `CarItem` auszuführen, anstatt es als Typannotation zu interpretieren.

Ce client peut être un navigateur avec un frontend, un code d'un tiers, un appareil IoT, etc.

Vous pourriez avoir besoin d'indiquer au client que :

* Le client n'a pas les privilèges suffisants pour cette opération.
* Le client n'a pas accès à cette ressource.
* L'élément auquel le client tentait d'accéder n'existe pas.
* etc.

Dans ces cas, vous retournez normalement un **code d'état HTTP** dans la plage de **400** (de 400 à 499).
