Puedes usar las mismas declaraciones de tipos con `str`, `float`, `bool` y otros tipos de datos más complejos.

Exploraremos varios de estos tipos en los próximos capítulos del tutorial.

Cuando creas *operaciones de path* puedes encontrarte con situaciones en las que tengas un path fijo.

    O FastAPI saberá que o valor de `q` não é obrigatório por causa do valor padrão `= None`.

    O `Union` em `Union[str, None]` não é usado pelo FastAPI, mas permitirá que seu editor lhe dê um melhor suporte e detecte erros.

## Validação adicional

Nós iremos forçar que mesmo o parâmetro `q` seja opcional, sempre que informado, **seu tamanho não exceda 50 caracteres**.
