That's sad. :-/

One of the reasons I implemented .items() is that I wanted
to increase the probability that at least *something* is
available instead of:

  for i in range(len(list):
      e = list[i]
      ...

or

  for i, e in zip(range(len(list)), list):
      ...

I'm going to teach Python to a lot of newbies (ca. 30) in
October. From my experience (I already tried my luck on two
individuals from that group) 'range(len(list))' is one
of the harder concepts to get across. Even indices(list)
would help here.
