Really! I stand corrected. I'm not a C programmer but I peeked at the source. I see that it makes a pass to calculate the total size and then another pass to catenate the items, which makes sense from a memory allocation standpoint. To compare and contrast, I looked up the 'sum' built in and saw that it used the iterator protocol, (PyObject_GetIter). I assume that the other similar functions (min,max, etc) would do the same. Thanks for setting me straight. ... Jay -- http://mail.python.org/mailman/listinfo/python-list
