Rule of thumb: If you want to add/remove arbitrary objects from a collection a dictionary (or set) is always faster than a list. You may still have to override the __eq__() and __hash__() methods whenever you have distinct objects that can be equal. Caveat: don't use dictionaries if the result of obj1 == obj2 # items in the dict can change during the lifetime of the collection. Peter -- http://mail.python.org/mailman/listinfo/python-list
