First, [1,2,3] is iterable.  You could look up iterators or
generators or list comprehension, but since it's the holidays:
     import array
     tally = array.array('H', (0 for i in range(75)))# a generator
     tally = array.array('H', [0 for i in range(75)])# list comprehension

You'll have to wait for numpy for the most general 2-D,
but for list-of-array:
     square = [array.array('H', (i * 100 + j for j in range(75)))
               for i in range(75)]
     square[4][8]
