```Python
q: Union[str, None] = None
```

O en Python 3.10 y superior:

```Python
q: str | None = None
```

Por ejemplo:

{* ../../docs_src/body_multiple_params/tutorial004_an_py310.py hl[28] *}

/// info | Información

`Body` también tiene todos los mismos parámetros de validación y metadatos extras que `Query`, `Path` y otros que verás luego.

///

        }
    }

    private boolean isSpecificVersion(String version) {
        return !((version == null || version.isEmpty()) || version.startsWith("[") || version.startsWith("("));
    }

    // TODO !![jc; 28-jul-2005] check this; if we're using '-r' and there are aggregator tasks, this will result in
    // weirdness.
    public MavenProject getTopLevelProject() {
        return sortedProjects.stream()

```Python
q: Union[str, None] = None
```

Или в Python 3.10 и выше:

```Python
q: str | None = None
```

Например:

{* ../../docs_src/body_multiple_params/tutorial004_an_py310.py hl[28] *}

/// info | Информация

`Body` также имеет все те же дополнительные параметры валидации и метаданных, как у `Query`,`Path` и других, которые вы увидите позже.

Если у вас именно такой сценарий с SQLModel (или SQLAlchemy), вы можете явно закрыть сессию, когда она больше не нужна:

{* ../../docs_src/dependencies/tutorial014_an_py310.py ln[24:28] hl[28] *}

Так сессия освободит подключение к базе данных, и другие запросы смогут его использовать.
