class Bar(object):
    def __init__(self, barnum):
        super(Bar, self).__init__()
        self.barnum = barnum

class DiamondProblem(Foo, Bar):
    # Arg order don't matter, since we call the `__init__`'s ourself.
    def __init__(self, barnum, mynum, foonum):
        Foo.__init__(self, foonum)
        Bar.__init__(self, barnum)

        self.mynum = mynum
