So würden Sie `Query()` als den Defaultwert Ihres Funktionsparameters verwenden und den Parameter `max_length` auf 50 setzen:

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

Wenn Sie jedoch dasselbe Modell als Ausgabe verwenden, wie hier:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py hl[19] *}

... dann, weil `description` einen Defaultwert hat, wird es, wenn Sie für dieses Feld **nichts zurückgeben**, immer noch diesen **Defaultwert** haben.
