## Eine „aufrufbare“ Instanz { #a-callable-instance }

In Python gibt es eine Möglichkeit, eine Instanz einer Klasse <abbr title="Englisch „callable“">„aufrufbar“</abbr> zu machen.

Nicht die Klasse selbst (die bereits aufrufbar ist), sondern eine Instanz dieser Klasse.

Dazu deklarieren wir eine Methode `__call__`:

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[12] *}

 * values are verified to ensure proper exception handling and byte
 * conversion.
