If the list is sorted, you can weed out the duplicates with itertools.groupby: >>> import itertools >>> L = [1,2,3,3,4,4,5] >>> [k for (k,_) in itertools.groupby(L, lambda x:x)] [1, 2, 3, 4, 5] HTH, -- Carsten Haese http://informixdb.sourceforge.net -- http://mail.python.org/mailman/listinfo/python-list
