利用yield,将函数变为生成器,同时可以实现.单线程下的并行.(简单的生产者消费者模型)

import time

def consumer(name):

    print("%s准备开始消费..."%name)

    while True:
        goods = yield
        if goods == "q":
            break
        else:
            print("%s 消费 %s"%(name, goods))

def produce(*consumers):

    for i in range(10):
        time.sleep(1)
        goods = "馒头[%d]"%i;
        for c in consumers:
            c.send(goods)

c1 = consumer("张飞")
c2 = consumer("李逵")
c1.__next__()
c2.__next__()
produce(c1, c2)

运行结果
