* <p>As an example, imagine that we have a list of tasks to execute, but we don't want to submit
 * more than 2 per second:
 *
 * <pre>{@code
 * final RateLimiter rateLimiter = RateLimiter.create(2.0); // rate is "2 permits per second"
 * void submitTasks(List<Runnable> tasks, Executor executor) {
 *   for (Runnable task : tasks) {
 *     rateLimiter.acquire(); // may wait
 *     executor.execute(task);
 *   }

A "**callable**" in Python is anything that Python can "call" like a function.

So, if you have an object `something` (that might _not_ be a function) and you can "call" it (execute it) like:

```Python
something()
```

or

```Python
something(some_argument, some_keyword_argument="foo")
```

then it is a "callable".

## Classes as dependencies

- For volumes that allow attaches across multiple nodes, attach and detach operations across different nodes are now executed in parallel. ([#89240](https://github.com/kubernetes/kubernetes/pull/89240), [@verult](https://github.com/verult)) [SIG Apps, Node and Storage]

  }

  /** @since 13.0 */
  @Override
  public final void addListener(Listener listener, Executor executor) {
    listeners.addListener(listener, executor);
  }

  @Override
  public String toString() {
    return getClass().getSimpleName() + " [" + state() + "]";
  }

  /**
   * Attempts to execute all the listeners in {@link #listeners} while not holding the {@link
   * #monitor}.
   */

```Python
some_variable: PlaneItem | CarItem
```

Mas se colocarmos isso em `response_model=PlaneItem | CarItem` teríamos um erro, pois o Python tentaria executar uma **operação inválida** entre `PlaneItem` e `CarItem` em vez de interpretar isso como uma anotação de tipo.

## Lista de modelos

Da mesma forma, você pode declarar respostas de listas de objetos.

    assertThat(dispatcher.queuedCalls()).isEmpty()
    assertThat(a1.isExecuted()).isTrue()
    assertThat(a1.isCanceled()).isFalse()
    assertThat(a2.isExecuted()).isTrue()
    assertThat(a2.isCanceled()).isTrue()
    assertThat(a3.isExecuted()).isFalse()
    assertThat(a3.isCanceled()).isTrue()
    assertThat(a4.isExecuted()).isFalse()
    assertThat(a4.isCanceled()).isFalse()
  }

  @Test

                    request.addHeader(header);
                }

                HttpEntity httpEntity = null;
                try {
                    final HttpResponse response = closeableHttpClient.execute(request, new BasicHttpContext(httpClientContext));
                    httpEntity = response.getEntity();
                    consumer.accept(response, httpEntity);
                } catch (final Exception e) {

## Motivations

Prenons un exemple simple :

{*../../docs_src/python_types/tutorial001.py*}

Exécuter ce programe affiche :

```
John Doe
```

La fonction :

* Prend un `first_name` et un `last_name`.
* Convertit la première lettre de chaque paramètre en majuscules grâce à `title()`.
