Problem

Lassen Sie Ihr Jahr als Prameter eingeben

Geben Sie "Drink toddy" zurück, wenn Sie unter 14 Jahre alt sind
Geben Sie "Cola trinken" zurück, wenn Sie unter 18 Jahre alt sind
Geben Sie "Bier trinken" zurück, wenn Sie unter 21 sind
Geben Sie "Whisky trinken" zurück, wenn Sie über 21 Jahre alt sind Schreiben wir die Funktion people_with_age_drink (age).

Sie müssen jedoch den folgenden Komponententest bestehen.

people_with_age_drink(13) == "drink toddy"
people_with_age_drink(17) == "drink coke"
people_with_age_drink(18) == "drink beer"
people_with_age_drink(20) == "drink beer"
people_with_age_drink(30) == "drink whisky"

Es scheint viele Antworten auf das FizzBuzz-Problem zu geben. Es wird oft gesagt, dass Python "ähnlicher Code ist, egal wer ihn schreibt", aber ich denke nicht.

Wie viel kennen Sie die Grundlagen von Python?
