When you iterate over rule, you don't iterate over the indices, but
over the values themselves. Try this:
for i in rule:
print i
Incidentally, "for i in range(rule)" isn't actually going to work;
what you would have used is "for i in range(len(rule))". Be careful
with that sort of thing; it's usually safest to actually copy and
paste from an interactive session, rather than reconstruct manually.
Sometimes it's not obvious whether it was a copy/paste problem or the
cause of your underlying confusion.
