Um zu unterscheiden zwischen Modellen für **Aktualisierungen**, mit lauter optionalen Werten, und solchen für die **Erzeugung**, mit benötigten Werten, können Sie die Techniken verwenden, die in [Extramodelle](extra-models.md){.internal-link target=_blank} beschrieben wurden.

Als je een recentere versie van Python kunt kiezen voor je project, kun je profiteren van die extra eenvoud.

In alle documentatie staan voorbeelden die compatibel zijn met elke versie van Python (als er een verschil is).

      // We use two volatile reads. We could reduce this to one by

      // the extra memory consumption and indirection are more
      // expensive than the extra volatile reads.

FastAPI supports dependencies that do some <abbr title='sometimes also called "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code", etc.'>extra steps after finishing</abbr>.

To do this, use `yield` instead of `return`, and write the extra steps (code) after.

/// tip

Make sure to use `yield` one single time per dependency.

[OkHttp 3.11][OkHttp311]
------------------------

_2018-07-12_

Added a new extra strict RESTRICTED_TLS configuration inspired by [Google Cloud’s similar policy][googlecloud_ssl_policy]. It is appropriate when both the host platform
(JVM/Conscrypt/Android) and target webserver are current.

    assertEquals("string+with+spaces", plusForSpaceEscaper.escape("string with spaces"));
    assertEquals("string with spaces", spaceEscaper.escape("string with spaces"));
  }

  /** Tests that if we add extra 'safe' characters they remain unescaped */
  public void testCustomEscaper() {
    UnicodeEscaper e = new PercentEscaper("+*/-", false);
    for (char c = 0; c < 128; c++) {
      if ((c >= '0' && c <= '9')

Щоб розрізняти моделі з усіма необов’язковими значеннями для **оновлення** і моделі з обов’язковими значеннями для **створення**, Ви можете скористатись ідеями, описаними у [Додаткові моделі](extra-models.md){.internal-link target=_blank}.

En este ejemplo, las *path operations* bajo el `router` usarán la clase personalizada `TimedRoute`, y tendrán un header `X-Response-Time` extra en el response con el tiempo que tomó generar el response:
