The same would happen if you had something like a <abbr title='A union between multiple types means "any of these types".'>union</abbr> between different types where one or more of them are not valid Pydantic types, for example this would fail 💥:

{* ../../docs_src/response_model/tutorial003_04_py310.py hl[8] *}

/// note | Hinweis

FastAPI weiß, dass der Wert von `q` nicht erforderlich ist, aufgrund des definierten Defaultwertes `= None`.

Das `str | None` (Python 3.10+) oder `Union` in `Union[str, None]` (Python 3.9+) wird von FastAPI nicht verwendet, um zu bestimmen, dass der Wert nicht erforderlich ist. FastAPI weiß, dass er nicht erforderlich ist, weil er einen Defaultwert von `= None` hat.

Lo mismo sucedería si tuvieras algo como un <abbr title='Una unión entre múltiples tipos significa "cualquiera de estos tipos".'>union</abbr> entre diferentes tipos donde uno o más de ellos no son tipos válidos de Pydantic, por ejemplo esto fallaría 💥:

{* ../../docs_src/response_model/tutorial003_04_py310.py hl[8] *}

/// note | Nota

FastAPI sabrá que el valor de `q` no es requerido debido al valor por defecto `= None`.

...это не сработает, потому что аннотация типа не является типом Pydantic и это не единственный класс `Response` или его подкласс, а объединение (`union`) из `Response` и `dict`.
