## Parâmetros opcionais { #optional-parameters }

Da mesma forma, você pode declarar parâmetros de consulta opcionais, definindo o valor padrão para `None`:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

Nesse caso, o parâmetro da função `q` será opcional, e `None` será o padrão.

/// check | Verifique

De la misma manera, puedes declarar parámetros de query opcionales, estableciendo su valor por defecto en `None`:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

En este caso, el parámetro de función `q` será opcional y será `None` por defecto.
