## Acerca de JWT

JWT significa "JSON Web Tokens".

Es un estándar para codificar un objeto JSON en un string largo y denso sin espacios. Se ve así:

```

    abstract int readBytesWireFormat(byte[] buffer, int bufferIndex);

    @Override
    public int hashCode() {
        return mid;
    }

    @Override
    public boolean equals(final Object obj) {
        return obj instanceof ServerMessageBlock && ((ServerMessageBlock) obj).mid == mid;
    }

    @Override
    public String toString() {
        String c = switch (command) {

            throw new AssertionFailedError("Don't iterate me!");
          }
        };
    assertEquals(5, Iterables.size(collection));
  }

  private static <T extends @Nullable Object> Iterable<T> iterable(T... elements) {
    List<T> list = asList(elements);
    return new Iterable<T>() {
      @Override
      public Iterator<T> iterator() {
        return list.iterator();

    };

Comme nous devons remplacer la valeur par défaut `None` dans la fonction par `Query()`, nous pouvons maintenant définir la valeur par défaut avec le paramètre `Query(default=None)`, il sert le même objectif qui est de définir cette valeur par défaut.

Donc :

```Python
q: Union[str, None] = Query(default=None)
```

... rend le paramètre optionnel, et est donc équivalent à :

```Python
