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... chris -- http://mail.python.org/mailman/listinfo/python-list
