Sie können die *Pfadoperationen* für dieses Modul mit `APIRouter` erstellen.

### `APIRouter` importieren

Sie importieren ihn und erstellen eine „Instanz“ auf die gleiche Weise wie mit der Klasse `FastAPI`:

```Python hl_lines="1  3" title="app/routers/users.py"
{!../../docs_src/bigger_applications/app/routers/users.py!}
```
