## Parámetros opcionales

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] *}

/// check | Revisa

Además, nota que **FastAPI** es lo suficientemente inteligente para notar que el parámetro de path `item_id` es un parámetro de path y `q` no lo es, por lo tanto, es un parámetro de query.

///

{* ../../docs_src/path_operation_configuration/tutorial005.py hl[21] *}

/// info | 정보

`response_description`은 구체적으로 응답을 지칭하며, `description`은 일반적인 *경로 작동*을 지칭합니다.

///

/// check | 확인

OpenAPI는 각 *경로 작동*이 응답에 관한 설명을 요구할 것을 명시합니다.

따라서, 응답에 관한 설명이 없을경우, **FastAPI**가 자동으로 "성공 응답" 중 하나를 생성합니다.

///

## 단일 *경로 작동* 지원중단

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

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

/// check | Verificar

Você também pode notar que o **FastAPI** é esperto o suficiente para perceber que o parâmetro da rota `item_id` é um parâmetro da rota, e `q` não é, portanto, `q` é o parâmetro de consulta.

///

        }
        return result.replaceAll("\\s+", " ");
    }

    /**
     * Returns the supported language for a given language.
     *
     * @param lang The language to check.
     * @return The supported language, or null if not supported.
     */
    protected String getSupportedLanguage(final String lang) {
        if (StringUtil.isBlank(lang)) {
            return null;
        }

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

In this case, the function parameter `q` will be optional, and will be `None` by default.

/// check

Also notice that **FastAPI** is smart enough to notice that the path parameter `item_id` is a path parameter and `q` is not, so, it's a query parameter.

///

   * array nor its contents can be null, but it is not useful to force the use of {@code
   * requireNonNull} or the like just to assert that.
   *
   * <p>{@code EqualsTester} will always check that every object it is given returns false from
   * {@code equals(null)}, so it is neither useful nor allowed to include a null value in any
   * equality group.
