Faire du code asynchrone signifie que le langage 💬 est capable de dire à l'ordinateur / au programme 🤖 qu'à un moment du code, il 🤖 devra attendre que *quelque chose d'autre* se termine autre part. Disons que ce *quelque chose d'autre* est appelé « slow-file » 📝.

And you get editor support everywhere.

Even for items inside of lists:

<img src="/img/tutorial/body-nested-models/image01.png">

You couldn't get this kind of editor support if you were working directly with `dict` instead of Pydantic models.

But you don't have to worry about them either, incoming dicts are converted automatically and your output is converted automatically to JSON too.

        int suppressed = runSuppressionFailureTest(in, out);
        assertThat(suppressed).isAtMost(1);
      }
    }
  }

  /**
   * @return the number of exceptions that were suppressed on the expected thrown exception
   */
  private static int runSuppressionFailureTest(CharSource in, CharSink out) {
    try {
      in.copyTo(out);
      fail();
    } catch (IOException expected) {

   * the behavior described in {@link #put(Range, Object) put(range, value)}, however the ranges
   * returned from {@link #asMapOfRanges} will be different if there were existing entries which
   * connect to the given range and value.
   *
   * <p>Even if the input range is empty, if it is connected on both sides by ranges mapped to the
   * same value those two ranges will be coalesced.

    void testInit() throws ServletException {
        assertDoesNotThrow(() -> ntlmServlet.init(servletConfig));
        // Further assertions can be added here to check the internal state of the servlet if fields were protected/public
    }
