## Paramètres optionnels

De la même façon, vous pouvez définir des paramètres de requête comme optionnels, en leur donnant comme valeur par défaut `None` :

{* ../../docs_src/query_params/tutorial002.py hl[9] *}

Ici, le paramètre `q` sera optionnel, et aura `None` comme valeur par défaut.

  * You can find out what taints you have in place on a node while you are still running Kubernetes 1.5 by doing `kubectl describe node <node name>`; the `Taints` section will show the taints you have in place. To see the taints that were created under 1.5 when you are running 1.6, do `kubectl get node <node name> -o yaml` and look for the "Annotation" section with the annotation key `scheduler.alpha.kubernetes.io/taints`

### Предупреждение о замене

Это означает, что если вы хотите обновить элемент `bar`, используя `PUT` с телом, содержащим:

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

поскольку оно не включает уже сохраненный атрибут `"tax": 20.2`, входная модель примет значение по умолчанию `"tax": 10.5`.

 * ### Query
 *
 * The query is optional: it can be null, empty, or non-empty. For many HTTP URLs the query string
 * is subdivided into a collection of name-value parameters. This class offers methods to set the
 * query as the single string, or as individual name-value parameters. With name-value parameters
 * the values are optional and names may be repeated.
