And now for a spot of silliness…

``````>>> a = [3, 5, 7]
>>> b = [8, 5, 3]
>>> c = zip(a, b[::-1])
>>> d = map(lambda x: set(x), c)
>>> e = filter(lambda x: len(x) != 1, list(d))
>>> list(e)
[{8, 7}]
>>> a = [3, 5, 7]
>>> b = [7, 5, 3]
>>> c = zip(a, b[::-1])
>>> d = map(lambda x: set(x), c)
>>> e = filter(lambda x: len(x) != 1, list(d))
>>> list(e)
[]
>>>
