Funktionen
Im Kontext eines Programms ist eine Funktion eine benannte Folge von Anweisungen, die eine Berechnung durchführen. Wenn Sie eine Funktion definieren, geben Sie einen Namen und die entsprechenden Anweisungen vor. Später können Sie dann diese Funktion über ihren Namen »aufrufen«.

>>> type(42)

Der Name der Funktion ist type. Den Ausdruck in Klammern nennt man das Argument der Funktion. Das Ergebnis der Funktion ist in diesem Fall der Typ des übergebenen Arguments.
Man spricht üblicherweise davon, dass eine Funktion ein Argument »erwartet« und ein Ergebnis »zurückliefert«. Das Ergebnis bezeichnet man auch als Rückgabewert.
