Get Weather!

[Dav1d]

Welche Liste? Meinst du das Wörterbuch mit den Tupeln? Warum soll es umständlicher sein, eine Liste zu benutzen als etwas zu zerlegen? Aber kann ja gut sein, dass man manche Schritte noch vereinfachen kann. Habe das nach bestem Wissen und Gewissen strukturiert.

Ah, stimmt, die Liste war in den alten 'Versionen'

Ich hab das komplette Skript nochmal überarbeitet, diesmal wird lxml oder BeautifulSouo verwendet, welches gerade installiert ist!
