Vous obtiendrez de l'autocomplétion dans du code que vous auriez pu considérer impossible auparavant. Par exemple, la clé `price` à l'intérieur d'un corps JSON (qui aurait pu être imbriqué) provenant d'une requête.

        "R0.20, R0.10, R0.10, R0.10"); // #7 (cont.), note, this matches #5
  }

  public void testBurstyAndUpdate() {
    RateLimiter rateLimiter = RateLimiter.create(1.0, stopwatch);
    rateLimiter.acquire(1); // no wait
    rateLimiter.acquire(1); // R1.00, to repay previous

    rateLimiter.setRate(2.0); // update the rate!

    rateLimiter.acquire(1); // R1.00, to repay previous (the previous was under the old rate!)

        "R0.20, R0.10, R0.10, R0.10"); // #7 (cont.), note, this matches #5
  }

  public void testBurstyAndUpdate() {
    RateLimiter rateLimiter = RateLimiter.create(1.0, stopwatch);
    rateLimiter.acquire(1); // no wait
    rateLimiter.acquire(1); // R1.00, to repay previous

    rateLimiter.setRate(2.0); // update the rate!

    rateLimiter.acquire(1); // R1.00, to repay previous (the previous was under the old rate!)

      assertWithMessage("Loader should NOT have been called @#%s", i)
          .that(loader.wasCalled())
          .isFalse();
    }

    // wait for entries to expire, but don't call expireEntries
    ticker.advance(EXPIRING_TIME * 10, MILLISECONDS);

    // add a single unexpired entry
    cache.getUnchecked(KEY_PREFIX + 11);

  - Select `Synchronization enabled` - `use settings from VCS` - `MyNewVcsRoot`(the one you just created) - `Settings format: Kotlin`, then `Apply`.
- At the popup window, click `Import Settings from VCS`. Wait a few seconds. 
  - If the error says "Context Parameter 'Branch' missing", it's ok. Click into the error and add a context parameter `Branch` with value `myTestBranch`. Go back and it automatically reloads.

백그라운드 작업으로 실행할 함수를 생성합니다.

이는 매개변수를 받을 수 있는 표준 함수일 뿐입니다.

`async def` 함수일 수도, 일반 `def` 함수일 수도 있으며, **FastAPI**가 이를 올바르게 처리하는 방법을 알고 있습니다.

이 경우 작업 함수는 파일에 쓰기를 수행합니다(이메일 전송을 시뮬레이션).

그리고 쓰기 작업은 `async`와 `await`를 사용하지 않으므로, 일반 `def`로 함수를 정의합니다:

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[6:9] *}

## 백그라운드 작업 추가 { #add-the-background-task }

*경로 처리 함수* 내부에서 `.add_task()` 메서드로 작업 함수를 *백그라운드 작업* 객체에 전달합니다:

Neste caso, a função da tarefa escreverá em um arquivo (simulando o envio de um e-mail).

E como a operação de escrita não usa `async` e `await`, definimos a função com um `def` normal:

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[6:9] *}

## Adicione a tarefa em segundo plano { #add-the-background-task }

        CountDownLatch latch = new CountDownLatch(shards.size());
        for (int i = 0; i < shards.size(); i++) {
            consumer.consumeResult(shards.get(i), () -> latch.countDown());
        }
        latch.await();
        SearchPhaseController.ReducedQueryPhase phase = consumer.reduce();
        executor.shutdownNow();
        return phase;
    }

    ImmutableList.Builder<Future<?>> futures = ImmutableList.builder();
    for (int i = 0; i < threadCount; i++) {
      futures.add(
          executor.submit(
              () -> {
                barrier.await();
                Integer first = graph.nodes().iterator().next();
                for (Integer node : graph.nodes()) {
                  Set<Integer> unused = graph.successors(node);
                }

C'est équivalent à :

```Python
