The thing is I am not really sure what I want.  I do know I need more
practice to find out.  Since I am taking a course now, I can't really
ask a direct question and my first example wasn't so good.

I think what I am going to have to have is a master list that keeps
track of several things and I will need to change some of them so I
know that rules out tuples.  

I need more practice examples with indexing and don't know where to
find it.

Thanks

It is hard to ask questions when you don't know all the terms yet.  I
also know that makes it even harder for you guys to answer them.  :)
