def iterman(self): yield "hello" yield "nice weather we're having" yield "goodbye" Which, more or less works, for a literal translation of the straw-man above. However, you're missing the point. These deferred operations actually return results. Generators offer no sane way to pass results back in.
that's why you need a context object (=self, in this case).
def iterman(self):
yield "hello"
print self.data
yield "nice weather we're having"
print self.data
yield "goodbye"also see:
