Wir importieren das Submodul `items` direkt, anstatt nur seine Variable `router` zu importieren.

Das liegt daran, dass wir im Submodul `users` auch eine weitere Variable namens `router` haben.

Wenn wir eine nach der anderen importiert hätten, etwa:

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

A maioria dessas configurações é variável (podem mudar), como URLs de bancos de dados. E muitas delas podem conter dados sensíveis, como tokens secretos.

Por isso é comum prover essas configurações como variáveis de ambiente que são utilizidas pela aplicação.
