Since Python supports multiple inheritance, you can't get away from something like super. Alternatives for methods chaining to parent classes are 1. implicit/automatic (like C++, I think), 2. explicit/semi-automatic (python's super, on one form or another, 3. explicit manual (programmer has to manually keep track of everything). Of all these alternatives I prefer Python's super (in one form or another). 1 is too "magic", and 3 is too error prone and cumbersome. A better question would be, is multiple inheritance good or bad for programs? :-) I think many people's answer to the above would be, generally bad, but there are exceptions where it helps and can be justified. > > > Regards, > > -- > .
