Mask superclass __init__

[Gribouillis]

Why do you want to hide it? It is very difficult to hide anything in python code.

Would a metaclass suit your needs?

class AutoSuperInitialized(type):
    def __new__(meta, name, superclasses, memberdict):
        i = '__init__'
        if i in memberdict:
            f = memberdict[i]
            def __init__(self, *args, **kwargs):
                super(cls, self).__init__(*args, **kwargs)
                f(self, *args, **kwargs)
            memberdict[i] = __init__
        cls = type.__new__(meta, name, superclasses, memberdict)
        return cls
    
    
class BaseClass(metaclass=AutoSuperInitialized):
    def __init__(self):
        print('BaseClass __init__ called!')
        
class OtherClass(BaseClass):
    def __init__(self):
        print('OtherClass __init__ called!')
        
if __name__ == '__main__':
    obj = OtherClass()

it works even with sub-sub-classes!
