### `yield from` { #yield-from }

Lorsque vous itérez sur quelque chose, comme un objet de type fichier, et que vous faites un `yield` pour chaque élément, vous pouvez aussi utiliser `yield from` pour émettre chaque élément directement et éviter la boucle `for`.

Ce n'est pas spécifique à FastAPI, c'est simplement Python, mais c'est une astuce utile à connaître. 😎

   * b}, then an {@code IndexOutOfBoundsException} is thrown. If {@code len} is zero, then no bytes
   * are read. Otherwise, the first byte read is stored into element {@code b[off]}, the next one
   * into {@code b[off+1]}, and so on. The number of bytes read is, at most, equal to {@code len}.

   * <p>If the {@link File} passed to one of the {@link Traverser} methods does not exist or is not
   * a directory, no exception will be thrown and the returned {@link Iterable} will contain a
   * single element: that file.
   *
   * <p>Example: {@code Files.fileTraverser().depthFirstPreOrder(new File("/"))} may return files
   * with the following paths: {@code ["/", "/etc", "/etc/config.txt", "/etc/fonts", "/home",

### `yield from` { #yield-from }

Wenn Sie über etwas iterieren, z. B. ein dateiähnliches Objekt, und dann für jedes Element `yield` verwenden, könnten Sie auch `yield from` verwenden, um jedes Element direkt weiterzugeben und die `for`-Schleife zu sparen.

Das ist nichts Spezifisches an FastAPI, das ist einfach Python, aber ein netter Trick. 😎
