If you're working with numbers, check out Numeric Python (NumPy), it's what
you want. Trust me. If your working with more general data types, you're
probably better off using nested lists. For example:

a =  [[[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]]]

would give you a 3D "array" with lots of silly numbers in it. Elements would
be accessed using "A[1][2][0]", etc.

If you want to use prettier indexing, you could roll your own class using
__getitem__ and __setitem__. I was going to provide an example, but work is
intruding, so maybe later.
