Оскільки за замовчуванням окремі значення інтерпретуються як параметри запиту, Вам не потрібно явно додавати `Query`, можна просто використати:

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

Або в Python 3.10 та вище:

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

Наприклад:

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


/// info | Інформація

}

#result .site cite {
	color: #093;
	font-style: normal;
}

#result .more {
	display: none;
}

#result .info {
	font-size: 80%;
}

#result .url-copy {
	color: #007bff;
}

#result .url-copied {
	color: #2c974b;
}

#result .favorited {
	display: none;
}

#result .favorited i {
	color: #fab005;
}

#result .thumbnail {
	width: 100px;

        elt = self.element.find('sts:{}'.format(name), _STS_NS)
        return STSElement(self.root_name, elt) if elt is not None else None

    def get_child_text(self, name, strict=True):
        """Extract text of a child element. If strict, and child element is
        not present, raises InvalidXMLError and otherwise returns
        None.

        """
        if strict:
            try:

 * or network should be done asynchronously.

abstract class EventListener {
  /**

Como, por defecto, los valores singulares se interpretan como parámetros de query, no tienes que añadir explícitamente un `Query`, solo puedes hacer:

```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] *}

## Optionale Parameter

Auf die gleiche Weise können Sie optionale Query-Parameter deklarieren, indem Sie deren Defaultwert auf `None` setzen:

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

In diesem Fall wird der Funktionsparameter `q` optional, und standardmäßig `None` sein.
