## Liste de modèles { #list-of-models }

De la même manière, vous pouvez déclarer des réponses contenant des listes d'objets.

Pour cela, utilisez le `list` Python standard :

## Réponse avec un `dict` arbitraire { #response-with-arbitrary-dict }

## Beschreibung der Response in der Dokumentation – OpenAPI { #documentation-response-description-openapi }

Um die Beschreibung der Response zu definieren, welche in der Oberfläche der Dokumentation angezeigt wird, lesen Sie die Dokumentation unter [Tutorial – Pfadoperation-Konfiguration – Beschreibung der Response](../tutorial/path-operation-configuration.md#response-description).
