Sorry to be so confusing. Just realized a dumb mistake I made. It doesn't need to be resorted alphabetically and numerically. I need one list alphabetical and one numerical.
(Alphabetical) List 1, [('Fred', 20), ('Joe', 90), ('Kent', 50), ('Sara', 80)]
(Numerical) List 2, [('Fred', 20), ('Kent', 50), ('Sara', 80) ('Joe', 90)]
It looks like these are appended together, but to re-sort, how do I (not sure if this is a word) "unappend" them?
Thanks,
Sara

You can supply your own comparison function to the sort routine.
You can also just specify the key to sort by for simple cases.

But you lost me here. You seem to be switching the values
in the tuples around and its not clear to me by what criteria.
