   This sample program will introduce you to "iteration" or
   "looping" over the characters in a string.

s = 'two kudus and a newt'

# What happens here?
for ch in s:
    print ch
print


# And here?
k = 0
while k < len(s):
    print s[k]
    k = k + 1
print

# Can you make sense of these structures?  Let's talk about
# them on Monday.  (You may find that the second section above
# can be modified nicely to do one of the hard parts of your
# homework--printing a string backwards.)
