   I thought this more elegant, but when I could not use the 'j' values
associated with each 'i' value I did some reading on sets. They are
iterable, but not indexable. And I need to access each 'j' associated with
each 'i'.

   But, I learned quite a bit. I think the groupby() approach is most
suitable for my need.

Thanks all,

Rich
