If you're actually working with filenames and paths then you should use os.path.basename() to get just the filename parts of the paths. test = set(map(os.path.basename, list1)) test |= set(map(os.path.basename, list2)) (Note: I *was* being stupid last night, the + operator doesn't work for sets. You want to use | ) Peace, ~Simon -- http://mail.python.org/mailman/listinfo/python-list
