Python使用迭代器捕获Generator返回值的方法

#!/usr/bin/env python
# -*- coding: utf-8 -*-
def fib(max):
  n, a, b = 0, 0, 1
  while n < max:
    yield b
    a, b = b, a + b
    n = n + 1
  return 'done'
# 捕获Generator的返回值
g = fib(6)
while True:
  try:
    x=next(g)
    print('g=',x)
  except StopIteration as e:
    print('Generrator return value:', e.value)
    break

g= 1
g= 1
g= 2
g= 3
g= 5
g= 8
Generrator return value: done
