Python ist eine interpretierte, hochentwickelte, universelle Programmiersprache. Im Gegensatz zu HTML, CSS und JavaScript, die hauptsächlich für die Webentwicklung verwendet werden, ist Python vielseitig einsetzbar und findet Anwendung in verschiedenen Bereichen, darunter Softwareentwicklung, Data Science und Back-End-Entwicklung. In diesem Kurs werden die zentralen Aspekte von Python behandelt, und am Ende werden Sie eigene Funktionen erstellen.

Erlernen des Einsatzes von Vergleichs- und logischen Operatoren, Arbeiten mit bedingten Ausdrücken sowie Anwendung von Mitgliedschafts- und Typvergleichen. Solide Grundlagen im Schreiben von Programmen, die mithilfe von if/else- und if/elif/else-Strukturen dynamisch auf unterschiedliche Bedingungen reagieren.

Herausforderung: Arbeiten mit Logischen Operatoren
