It's always nice to know there are such good-natured people ready to
help on this group. 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]], [])
On an unrelated note, can anyone explain this unpredictable behavior on
IDLE? I swear I never hit ctrl-c...
==============================
>>> help(sum)
Help on built-in function sum in module __builtin__:
sum(...)
sum(sequence, start=0) -> value
Returns the sum of a sequence of numbers (NOT strings) plus the
value
of parameter 'start'. When the sequence is empty, returns start.
Traceback (most recent call last):
