    Então, você deve declará-lo com `...` para marcá-lo como obrigatório.

    Mesmo que você declare-o como `None` ou defina um valor padrão, isso não teria efeito algum, o parâmetro ainda seria obrigatório.

## Ordene os parâmetros de acordo com sua necessidade

Suponha que você queira declarar o parâmetro de consulta `q` como uma `str` obrigatória.
