Generating Multiple Class Instances

We have a winner! D-man's code most closely resembles what I want to do:

This way, I can also have a line:

print flavor['up'].color

extracting a single element.  This is something I haven't been able to get
most other suggested code to do, though I'm still looking into all the
suggestions.

I like this too, but I think it suffers from the problem above.  To access
the color of the top, I have to know the place of the "top" instance in the
list  (called "topindex" below)...

print flavor[topindex].color

...the whole point is so that I don't have to remember where each guy is in
the list.

Thanks for the assist.
