Python Question

I have the following tuples

`tups = zip(list('AAAABBBB'), zip(list('aabbaabb'), list('cdcdcdcd')))`

tups

[('A', ('a', 'c')),

('A', ('a', 'd')),

('A', ('b', 'c')),

('A', ('b', 'd')),

('B', ('a', 'c')),

('B', ('a', 'd')),

('B', ('b', 'c')),

('B', ('b', 'd'))]

I'd like to create a pandas MultiIndex from them

`df = pd.DataFrame(np.arange(32).reshape(4, 8),`

columns=pd.MultiIndex.from_tuples(tups))

But I get tuples in a second level. How do I get all three levels?

`print df`

A B

(a, c) (a, d) (b, c) (b, d) (a, c) (a, d) (b, c) (b, d)

0 0 1 2 3 4 5 6 7

1 8 9 10 11 12 13 14 15

2 16 17 18 19 20 21 22 23

3 24 25 26 27 28 29 30 31
