Tony,
Actually I only want to remove a certain kind of duplication; if an item occurs twice - say like this: [1,1,1,2,2,2,1,1,1], then I need to keep the order and occurrence of the individual values: [1,2,1]. Using a dict as you proposed loses the order of occurrence, as well as multiple occurrences of groups of the same item.
If I didn't need those two qualities of the list to be preserved, though, I think I'd use something like your solution (if I was using a Python older than 2.3) or Steve Coats' solution posted above using Set.
Thanks! Alan

Here is a version using dictionary properties, ie no duplication of keys.
def condense(l): d={} for item in l: d[item]=1 l=d.keys() return l
