Kapitel 3: Klassen und Vererbung
Als objektorientierte Programmiersprache unterstützt Python eine Vielzahl von Features wie Vererbung, Polymorphismus und Verkapselung. Um in Python Aufgaben erledigen zu können, ist es oftmals erforderlich, neue Klassen zu programmieren und festzulegen, wie sie durch ihre Schnittstellen und Hierarchien miteinander interagieren.
Klassen und Vererbung erleichtern es in Python, das beabsichtigte Verhalten eines Programms durch Objekte zu modellieren. Sie gestatten es, Funktionalitäten im Laufe der Zeit allmählich zu verbessern und auszubauen. Sie passen sich flexibel an Umgebungen mit wechselnden Anforderungen an. Der gekonnte Umgang mit Klassen gestattet es, wartungsfreundlichen Code zu schreiben.
