Chapter 10. while und for-Schleifen
In diesem Kapitel lernen Sie die zwei wichtigsten Schleifen konstrukte in Python kennen, d.h. Anweisungen, die eine Aktion wiederholen. Die erste, die while-Anweisung, bietet eine Möglichkeit, allgemeine Schleifen zu codieren. Und die zweite, die for-Anweisung, ist für die schrittweise Iteration über die Elemente einer Sequenz gedacht und führt für jedes Element einen Codeblock aus.
Es gibt noch weitere Schleifenoperationen in Python, aber die hier behandelten zwei Anweisungen sind die Hauptsyntax für die Codierung wiederholter Aktionen. Wir werden hier auch einige eher unübliche Anweisungen wie break und continue vorstellen, weil sie - sofern überhaupt - in Schleifen benutzt werden.
