  `Keep your temper,' said the Caterpillar.

  `Is that all?' said Alice, swallowing down her anger as well as
she could.

  `No,' said the Caterpillar.

  Alice thought she might as well wait, as she had nothing else
to do, and perhaps after all it might tell her something worth
hearing.  For some minutes it puffed away without speaking, but
at last it unfolded its arms, took the hookah out of its mouth

# Concurrence et async / await { #concurrency-and-async-await }

Détails sur la syntaxe `async def` pour les *fonctions de chemin d'accès* et quelques rappels sur le code asynchrone, la concurrence et le parallélisme.

<abbr title="too long; didn't read - trop long ; pas lu"><strong>TL;DR :</strong></abbr>

Si vous utilisez des bibliothèques tierces qui nécessitent d'être appelées avec `await`, telles que :

```Python

            }

            else if (type == 'progress') {
                await this.progress(line);
                await this._wait(delay);
            }

            else {
                this.container.appendChild(line);
                await this._wait(delay);
            }

            line.removeAttribute(`${this.pfx}-cursor`);
        }
        this.addRestart()

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[9:12] *}

C'est l'équivalent de :

```Python
response = client.get('/')
```

... que nous utilisions pour faire nos requêtes avec le `TestClient`.

/// tip | Astuce

Notez que nous utilisons async/await avec le nouveau `AsyncClient` — la requête est asynchrone.

///

      createUnreachableLatchFinalizer(done);
      await(done);
      if (predicate.isDone()) {
        return;
      }
    } while (System.nanoTime() - deadline < 0);
    throw formatRuntimeException(
        "Predicate did not become true within %d second timeout", timeoutSeconds);
  }

  /**
   * Waits until the given latch has {@linkplain CountDownLatch#countDown counted down} to zero,

/// note | Technical Details

An `async` task can only be cancelled when it reaches an `await`. If there is no `await`, the generator (function with `yield`) can not be cancelled properly and may keep running even after cancellation is requested.

Since this small example does not need any `await` statements, we add an `await anyio.sleep(0)` to give the event loop a chance to handle cancellation.

    * Flatbuffer version update:
        * `GetTemporaryPointer()` bug fixed.

* `tf.data`
    * Add `wait` to `tf.data.Dataset.load`. If `True`, for snapshots written with `distributed_save`, it reads the snapshot while it is being written. For snapshots written with regular `save`, it waits for the snapshot until it's finished. The default is `False` for backward compatibility. Users of `distributed_save` are recommended to set it to `True`.

Let's look at how we can make that work.
