Brandon, this example might help you understand the problem: >>> def g(): print('p1') yield 2 print('p3') >>> g() <generator object g at 0x00F04DC8> >>> b=g() >>> next(b) p1 2 >>> next(b) p3 Traceback (most recent call last): File "<pyshell#24>", line 1, in <module> next(b) StopIteration >>> -- http://mail.python.org/mailman/listinfo/python-list
