### Namenskollisionen vermeiden

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:

/// note | "Technische Details"

Das geschieht nur, wenn Sie die Installation mit der enthaltenen `requirements.txt` durchführen, anstatt `pip install fastapi` direkt auszuführen.

Das liegt daran, dass in der Datei `requirements.txt` die lokale Version von FastAPI mit der Option `-e` für die Installation im „editierbaren“ Modus markiert ist.
