Je vais vous montrer certains des principaux concepts que vous devriez probablement avoir à l'esprit lors du déploiement
d'une application **FastAPI** (bien que la plupart de ces concepts s'appliquent à tout autre type d'application web).

Nous importons le sous-module `items` directement, au lieu d'importer uniquement sa variable `router`.

C'est parce que nous avons également une autre variable nommée `router` dans le sous-module `users`.

Si nous les avions importées l'une après l'autre, comme :

```Python
from .routers.items import router
from .routers.users import router
```
