A dictionary's values don't have to be hashable, so if the keywords are the keys in the dictionary, this would work. >>> d = {} >>> d['key1'] = [1,2,3] >>> d['key2'] = [4,5,6] >>> d {'key2': [4, 5, 6], 'key1': [1, 2, 3]} > I don't mind making my lists immutable.

[a for a in list] (or a[:]) makes a copy of a list. Putting parentheses around a list does absolutely nothing. You then assign the copied list to the 'mykey' index in the dictionary. =Tony.Meyer -- http://mail.python.org/mailman/listinfo/python-list
