## Reduzir duplicação

Reduzir a duplicação de código é uma das ideias principais no **FastAPI**.

A duplicação de código aumenta as chances de bugs, problemas de segurança, problemas de desincronização de código (quando você atualiza em um lugar, mas não em outros), etc.

E esses modelos estão compartilhando muitos dos dados e duplicando nomes e tipos de atributos.

   * insists upon doing. It then runs the test, which behaves exactly like this package's existing
   * PackageSanityTests. (The test would run on the JVM, too, if not for the suppression below, and
   * that would be a problem because it violates small-test rules. Note that we strip the
   * suppression externally, but it's OK because we don't enforce test-size rules there.)

Bevorzugen Sie die `Annotated`-Version, falls möglich.

Aber bedenken Sie, dass Sie dieses Problem nicht haben, wenn Sie `Annotated` verwenden, da Sie nicht die Funktions-Parameter-Defaultwerte für `Query()` oder `Path()` verwenden.

         * We'd like to simply create our own TypeVariable with the newly resolved bounds. There's
         * just one problem: Under all the JDK versions that we support (though *not* under
         * Android), the built-in TypeVariable's equals() method doesn't recognize instances of our
         * TypeVariable implementation. This is a problem because users compare TypeVariables from

Ainsi, vous pouvez déclarer votre fonction comme suit :

Mais gardez à l'esprit que si vous utilisez `Annotated`, vous n'aurez pas ce problème, cela n'aura pas d'importance car vous n'utilisez pas les valeurs par défaut des paramètres de fonction pour `Query()` ou `Path()`.

Es gibt mehrere Flask REST Frameworks, aber nachdem ich die Zeit und Arbeit investiert habe, sie zu untersuchen, habe ich festgestellt, dass viele nicht mehr unterstützt werden oder abgebrochen wurden und dass mehrere fortbestehende Probleme sie unpassend machten.
