There's a lot of parenthesis :) not easy to read, but unless I'm seeing something odd, you have string literals in a tuple. So I don't think your going to find a better way than brute force recreation. FYI lists are between [] and are mutable Tuples are between () and are immutable. If I'm countin paren's right you have a list that contains a tuple, that contains another tuple with 1 element in it. so you can recreate the tuples... or convert the whole thing to a list of lists. -- http://mail.python.org/mailman/listinfo/python-list
