Here is where I see the break in the 'flow': >>> 1+2+3 6 >>> sum([1,2,3], 0) 6 >>> [1] + [2] +[3] [1, 2, 3] >>> sum([[1],[2],[3]], []) [1, 2, 3] >>> '1' + '2' + '3' '123' >>> sum(['1','2','3'], '') Traceback (most recent call last): File "<interactive input>", line 1, in ? TypeError: sum() can't sum strings [use ''.join(seq) instead] >>> - Pad. -- http://mail.python.org/mailman/listinfo/python-list
