Python 2.x super __init__ inheritance doesn't work when parent doesn't inherit from object

Question

I have the following Python 2.7 code:

class Frame:
    def __init__(self, image):
        self.image = image

class Eye(Frame):
    def __init__(self, image)         


        

Answer 1

Frame must extend object because only the new style classes support super call you make in Eye like so:

class Frame(object):
    def __init__(self, image):
        self.image = image

class Eye(Frame):
    def __init__(self, image):
        super(Eye, self).__init__(image)
        self.some_other_defined_stuff()
