Python USES an iterator to capture the method of the return value of Generator

This example shows how Python USES an iterator to capture the return value of Generator. I will share it with you for your reference as follows:

When calling generator with the for loop, the return value of generator's return statement is not found. If you want to get the return value, you must catch the StopIteration error, which is contained in value of StopIteration:

#!/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'
#  capture Generator The return value of the 
g = fib(6)
while True:
  try:
    x=next(g)
    print('g=',x)
  except StopIteration as e:
    print('Generrator return value:', e.value)
    break

Output:

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