This will fail when iter1 yields one more item than iter2. izip() then consumes one extra item: >>> from itertools import izip >>> a = iter([1,2]) >>> list(izip(a, "b")) [(1, 'b')] >>> a.next() Traceback (most recent call last): File "<stdin>", line 1, in <module> StopIteration Peter -- http://mail.python.org/mailman/listinfo/python-list
