L’objectif était d’éviter de conserver des ressources plus longtemps que nécessaire pendant que la réponse transitait sur le réseau.

Ce changement impliquait aussi que si vous retourniez une `StreamingResponse`, le code d’arrêt de la dépendance avec `yield` aurait déjà été exécuté.

Vous pouvez ensuite définir le `status_code` dans cet objet de réponse *temporaire*.

{* ../../docs_src/response_change_status_code/tutorial001_py310.py hl[1,9,12] *}

Vous pouvez ensuite renvoyer n'importe quel objet nécessaire, comme d'habitude (un `dict`, un modèle de base de données, etc.).

Et si vous avez déclaré un `response_model`, il sera toujours utilisé pour filtrer et convertir l'objet que vous avez renvoyé.

It might also help avoid confusion for new developers that see an unused parameter in your code and could think it's unnecessary.
