What makes an iterator an iterator?

[Isaac Rodriguez]

Sorry, my previous post was incomplete. I didn't realized that you
implemented _next() as a generator funcition. Besides changing
__init__() from

    self.next = self._next()

to
    self.next = self._next

you need to implement __iter__() as:

    return self.next()
