Kleines Python Spiel

Das folgende Spiel hab ich aus dem Buch „Programmieren supereasy: Einfacher Einstieg in SCRATCH und PYTHON“ 978-3831027002 übernommen. Das tolle an der Scriptsprache Python ist, dass es auch einen Interpreter für das Android System gibt. Somit kann das Spiel auf vielen System laufen.
