Hello! Thanks to all for the very interesting postings!
I came to the following: For single inheritance, super is a nice tool if you will recfactoring the class later. For multiple inheritance, if you want to use super, you have to have very much knowledge of the classes you inheritance. For me, OOP is to not have to have the deep inner knowledge of the classes I inheritance from. Also, for multiple inheritance, if think Mother1.__init__(self, ...) Mother2.__init__(self, ...) Mother3.__init__(self, ...) would be more clear to read then super(MyClass).__init__(Maby this will do some magic thing) Also, I realy dislike __init__(self, param, **eat_some_needless_stuff) If I later extend my class and also add some parameters to __init__, what will happen to the classes using the baseclass? Also, lool at that: class Mother(object): def __init__(self, param_mother='optional', **eat): print 'Mother' class Father(object): def __init__(self, param_father='optional', **eat): print 'Father' class Child(Mother, Father): def __init__(self, **ham): super(Child, self).__init__(**ham) child = Child(param_mother=1, param_father=1) Father's init will not be called.
