Si simplemente no lo sabes, usa `def` normal.

---

**Nota**: puedes mezclar `def` y `async def` en tus *path operation functions* tanto como lo necesites y definir cada una utilizando la mejor opción para ti. FastAPI hará lo correcto con ellos.

```Python
images: List[Image]
```

como em:

```Python hl_lines="15"
{!../../../docs_src/body_nested_models/tutorial008.py!}
```

!!! check "Revisa"
    También puedes notar que **FastAPI** es lo suficientemente inteligente para darse cuenta de que el parámetro de path `item_id` es un parámetro de path y que `q` no lo es, y por lo tanto es un parámetro de query.

!!! note "Nota"
    FastAPI sabrá que `q` es opcional por el `= None`.
