I want to thank Morn for the nice pun I used as title.
Update: Teh Mornster has flexed his mighty Python-Fu by showing me an easier way (second line). I remember starting out like this, but something didn’t work, so I tried another way (first line) which worked good. His idea is more elegant, tho. Thanks!
