[Tutor] List Dup-Elim Method?

I'm working on a similar problem, but more complicated and involving a
zillion real world variables. I haven't fully worked it out yet, but here
are some thoughts that might help you out.
If the list isn't 200,000 items long or something, you can try a brute force
approach. For each item of the list, compare the item to each other item,
deleting duplicates as you go, then drop a copy of that item into a new
Or, do the same thing, but instead of deleting the dupes as you go, move
them into a *dupes* list, and copy the first item into a new list.
if mylist[0:1] == mylist[1:2]:
mylist[1:2] = 
This code compares an item in a list to the item next to it. If the two
items are equivalent, the second item is essentially removed.
Hope this helps a bit,
