sera valide comme dépendance **FastAPI**.

En fait, FastAPI utilise ces deux décorateurs en interne.

## Créer une dépendance de base de données avec `yield` { #a-database-dependency-with-yield }

Par exemple, vous pouvez l'utiliser pour créer une session de base de données et la fermer après la fin.

Seul le code précédant et incluant l'instruction `yield` est exécuté avant la création de la réponse :
