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
>>>
