Zum Beispiel ist das nicht erlaubt:

```Python
q: Annotated[str, Query(default="rick")] = "morty"
```

... denn es ist nicht klar, ob der Defaultwert `"rick"` oder `"morty"` sein soll.

Sie würden also (bevorzugt) schreiben:

```Python
q: Annotated[str, Query()] = "rick"
```

... oder in älteren Codebasen finden Sie:

    app = FastAPI()
    router = APIRouter()


    @router.get("/users/", tags=["users"])
    async def read_users():
        return [{"username": "Rick"}, {"username": "Morty"}]


    app.include_router(router)
    ```
    """

    def __init__(
        self,
        *,
        prefix: Annotated[str, Doc("An optional path prefix for the router.")] = "",

```Python
from fastapi import Depends, FastAPI, HTTPException
from typing_extensions import Annotated

app = FastAPI()


data = {
    "plumbus": {"description": "Freshly pickled plumbus", "owner": "Morty"},
    "portal-gun": {"description": "Gun to create portals", "owner": "Rick"},
