Students tend to do this because it save a little typing, but it's
generally considered a bad idea in anything but the shortest programs.

One thing that would help a lot would be to stop relying on getting the
order exactly right.  You could, at the expense of more typing, use
assignments:

  obj['!'] = "exclamation mark";

This would make any errors obvious.

And then, if you wanted to try something a little more sophisticated,
you could use a loop for the digits and the letters.
