Nehmen wir an, Sie möchten, dass der `q` Query-Parameter eine `min_length` von `3` hat und einen Defaultwert von `"fixedquery"`:

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

/// note | Hinweis

Ein Defaultwert irgendeines Typs, einschließlich `None`, macht den Parameter optional (nicht erforderlich).
