Você pode, claro, usar valores padrão diferentes de `None`.

Digamos que você queira declarar o parâmetro de consulta `q` com `min_length` de `3` e ter um valor padrão de `"fixedquery"`:

{* ../../docs_src/query_params_str_validations/tutorial005_an_py39.py hl[9] *}

/// note | Nota

Ter um valor padrão de qualquer tipo, incluindo `None`, torna o parâmetro opcional (não obrigatório).
