  1. docs/zh/docs/tutorial/query-params-str-validations.md

    ```
    
    由于我们必须用 `Query(default=None)` 替换默认值 `None`,`Query` 的第一个参数同样也是用于定义默认值。
    
    所以:
    
    ```Python
    q: Union[str, None] = Query(default=None)
    ```
    
    ...使得参数可选,等同于:
    
    ```Python
    q: str = None
    ```
    
    但是 `Query` 显式地将其声明为查询参数。
    
    然后,我们可以将更多的参数传递给 `Query`。在本例中,适用于字符串的 `max_length` 参数:
    
    ```Python
    q: Union[str, None] = Query(default=None, max_length=50)
    ```
    
    将会校验数据,在数据无效时展示清晰的错误信息,并在 OpenAPI 模式的*路径操作*中记录该参​​数。

  2. docs/fr/docs/tutorial/query-params-str-validations.md

    Le paramètre de requête `q` a pour type `Union[str, None]` (ou `str | None` en Python 3.10), signifiant qu'il est de type `str` mais pourrait aussi être égal à `None`, et bien sûr, la valeur par défaut est `None`, donc **FastAPI** saura qu'il n'est pas requis.
    
    /// note
    
    **FastAPI** saura que la valeur de `q` n'est pas requise grâce à la valeur par défaut `= None`.

  3. docs/ko/docs/tutorial/query-params-str-validations.md

    ```Python hl_lines="9"
    {!../../docs_src/query_params_str_validations/tutorial001.py!}
    ```
    
    쿼리 매개변수 `q`는 `Optional[str]` 자료형입니다. 즉, `str` 자료형이지만 `None` 역시 될 수 있음을 뜻하고, 실제로 기본값은 `None`이기 때문에 FastAPI는 이 매개변수가 필수가 아니라는 것을 압니다.
    
    /// note | "참고"
    
    FastAPI는 `q`의 기본값이 `= None`이기 때문에 필수가 아님을 압니다.
    
    `Optional[str]`에 있는 `Optional`은 FastAPI가 사용하는게 아니지만, 편집기에게 더 나은 지원과 오류 탐지를 제공하게 해줍니다.

  4. docs/pt/docs/tutorial/query-params-str-validations.md

    ```
    
    O parâmetro de consulta `q` é do tipo `Union[str, None]`, o que significa que é do tipo `str` mas que também pode ser `None`, e de fato, o valor padrão é `None`, então o FastAPI saberá que não é obrigatório.
    
    /// note | "Observação"
    
    O FastAPI saberá que o valor de `q` não é obrigatório por causa do valor padrão `= None`.
