All the indexing and slicing that works on arrays also works on strings. Use # some kind of explanation to add comments to programs. Use numpy.mean(array), numpy.max(array), and numpy.min(array) to calculate simple statistics. Use numpy.mean(array, axis=0) or numpy.mean(array, axis=1) to calculate statistics across the specified axis.
