  ^^^  Right... I get this:
>>> blah = ['buh', 'blah', 'wassah']
>>> blah[1][0]
'b'
^^^

Formatted for clarity:

>>> m = [[1,2,3],
         [4,5,6],
         [7,8,9]]
>>> m[1][1]
5

>>> m3 = [[[1,2,3],   [4,5,6],   [7,8,9]   ],
          [[11,12,13],[14,15,16],[17,18,19]],
          [[21,22,23],[24,25,26],[27,28,29]]]
>>> m3[1][1][1]
15
