any special reason why you keep pretending that some random wikipedia editor knows more about a future Python release than the people that develops Python ? > Anyway, I figured out a way to get the builtin > function 'sum' to work as I need: > sum([[1,2,3],[4,5,6],[7,8,9]], []) sum() is designed for adding numbers, not sequences. abusing it for sequences leads to inefficient code, and extremely bad worst- case behaviour, since you end up copying the same data over and over and over again -- the function even checks for strings for this very reason: >>> sum(["123", "456", "789"], "") Traceback (most recent call last): File "<stdin>", line 1, in ? TypeError: sum() can't sum strings [use ''.join(seq) instead] (maybe it should check for other well-known containers as well?) if you care about writing robust code, why not just use a for-loop, and the list extend method? </F> -- http://mail.python.org/mailman/listinfo/python-list
