class Foo(object): def __init__(self): self.__method() def __method(self): print('42') class MoreFoo(Foo): def __method(self): print('41') MoreFoo()
As __method() is a private method (recognisable by the double underscores __ ), it cannot be overridden by simply defining it as __method(self) in the subclass (to avoid accidental override). To force overridding, it has to be redefined as def _Foo__method(self): . This is called name mangling. (stackoverflow.com/questions/14898197/override-private-met...)
