thanks (also to Steven) for the info, that is exactly what i was looking 
for.

reason is that I built a small UI in which the user may choose if he 
want to do a split, findall (and maybe later others like match or 
search). So the method name comes in "from the UI". I could of course 
use if/elif/else blocks but thought getattr should be shorter and 
easier. I was not really aware of getattr which I was looking for on 
other occations before...
