Por exemplo, o modelo acima declara um JSON "`object`" (ou `dict` no Python) como esse:

```JSON
{
    "name": "Foo",
    "description": "Uma descrição opcional",
    "price": 45.2,
    "tax": 3.5
}
```

...como `description` e `tax` são opcionais (Com um valor padrão de `None`), esse JSON "`object`" também é válido:

```JSON
{

<%@page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%>
<footer class="main-footer">
	<div class="float-right d-none d-sm-inline-block"></div>
	<la:message key="labels.footer.copyright" />

    for prod and one for tests. However, unlike our other packages, as of this
    writing it has test supersource but no prod supersource.

    GWT happens to use the prod .gwt.xml, so it looks for no supersource for
    tests, either. This causes it to fail to find AtomicLongMapTest.

    Our workaround is to tell GWT that util.concurrent and all other packages

## URL-адреси документації

Ви можете налаштувати два інтерфейси користувача для документації, які включені:

* **Swagger UI**: доступний за адресою `/docs`.
    * Ви можете змінити його URL за допомогою параметра `docs_url`.
    * Ви можете вимкнути його, встановивши `docs_url=None`.
* **ReDoc**: доступний за адресою `/redoc`.

ret=$?

if [ $ret != 0 ] ; then
  for f in `find ./target -type f | grep surefire-reports | grep -v /TEST-` ; do
    cat $f
  done
fi

                        final String sid = crawler.getCrawlerContext().getSessionId();

In this scenario, each one of the cleaners (including you) would be a processor, doing their part of the job.

* `limit=10`: çünkü varsayılan değer buydu.

## İsteğe Bağlı Parametreler

Aynı şekilde, varsayılan değerlerini `None` olarak atayarak isteğe bağlı parametreler tanımlayabilirsiniz:

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

Bu durumda, `q` fonksiyon parametresi isteğe bağlı olacak ve varsayılan değer olarak `None` alacaktır.
