python之协程--最简单的代码

# Author: xueyou

import time
def consumer(name):
    print("%s 准备吃包子啦!" %name)
    while True:
       baozi = yield

       print("包子[%s]来了,被[%s]吃了!" %(baozi,name))

# c = consumer("ChenRonghua")
# c.__next__()

# b1= "韭菜馅"
# c.send(b1) # 调用并且给yield传值
# c.__next__() #只继续调用，所以打印的结果是包子[none]来了
