6Schleifen
Schleifen dienen der wiederholten Ausführung von einer oder mehreren Anweisungen. In der Programmierung werden verschiedene Schleifenarten unterschieden.
Die Zählschleife: Die enthaltenen Anweisungen werden ausgeführt, bis ein gewisser Zählerstand erreicht ist. Viele Programmiersprachen enthalten diese Funktionalität in Form der for-Schleife. In Python wird statt eines Zählers eine Sequenz durchlaufen.
Die bedingte Schleife: Hier werden die Anweisungen erst nach einem Test ausgeführt. Dieser Test wird vor jedem Durchlauf der Schleife erneut ausgeführt, und die Anzahl der Schleifendurchläufe ist nicht genau festgelegt. Dieser Typ Schleife wird mit dem Schlüsselwort while eingeleitet.
