print(school)Die Fehlermeldungen sind dazu da, dir zu helfen. Fehlermeldungen zu lesen und zu verstehen ist eins der wichtigsten Dinge, die man lernen muss, weil Fehlermeldungen der Weg sind, mit der dir Python sagt, was du wo falsch gemacht hast. Also musst du die Fehlermeldungen entweder selbst lesen, oder (zusammen mit dem passenden Code) hier zeigen, damit wir Hinweise geben können, die dir helfen, die Fehlermeldungen zu verstehen.martin2p hat geschrieben: Mittwoch 25.
