The super() function allows you to access methods in the parent x that are shadowed by methods of the same name in the child y.

In this case, y.__init__ wants to call x.__init__. But the problem is that y.__init__ clobbers __init__ in the namespace; that is, x.__init__ doesn't get inherited. SO, super(y, self) returns x, so that your code means this:

class x(object):
    def __init__(self):
        self.x=1

class y(x):
    def __init__(self):
        x.__init__(self)
