  Ask user if query_item will be enabled. Default is used if no input is given.

Da einfache Werte standardmäßig als Query-Parameter interpretiert werden, müssen Sie `Query` nicht explizit hinzufügen, Sie können einfach schreiben:

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

Oder in Python 3.10 und darüber:

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

Zum Beispiel:

{* ../../docs_src/body_multiple_params/tutorial004_an_py310.py hl[27] *}

/// info

As, by default, singular values are interpreted as query parameters, you don't have to explicitly add a `Query`, you can just do:

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

Or in Python 3.10 and above:

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

For example:

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


/// info

                (jsonObject["parallelizationMethod"] as? Map<*, *>)?.let { objectMapper.valueToTree<JsonNode>(it) }
                    ?: return None

            return when (methodJsonNode.get("name")?.asText()) {
                null -> None
                None::class.simpleName -> None
                TestDistribution::class.simpleName -> TestDistribution
                TestDistributionAlpine::class.simpleName -> TestDistributionAlpine

public interface Language extends ExtensibleEnum {

    /**
     * The "none" language. It is not versioned, family is same to itself, and compatible with itself only.
     * In turn, every {@link Language} implementation must be compatible with {@code NONE} language.

    Language NONE = language("none");

    /**
     * The "resources" language. This is used for files such as images to provide in the output.

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

Ou como em Python 3.10 e versões superiores:

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

Por exemplo:

{* ../../docs_src/body_multiple_params/tutorial004_py310.py hl[26] *}

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] *}
