Answer 1

The most obvious method I can think of for this would be a user defined type that would remember the summary for you..

>>> import random
>>> class ValueProducer:
...    def produce_values(self, n):
...        self._total = 0
...        for i in range(n):
...           r = random.randrange(n*100)
...           self._total += r
...           yield r
...        self.value_summary = self._total/n
...        return self.value_summary
... 
>>> v = ValueProducer()
>>> for i in v.produce_values(3):
...    print(i)
...

>>> print(v.value_summary)
