python学习之路：生成器并行运算

Posted 2020-10-16 Py小白

异步IO的雏形：

简单的单线程下的并行效果

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__()#调用只唤醒 yield

# b1="韭菜馅"
#
# c.send(b1)#调用yield并传值
#c.__next__()

def producer(name):
    c = consumer(‘A‘)
    c2 = consumer(‘B‘)
    c.__next__()
    c2.__next__()
    print("老子开始准备做包子啦！")
    for i in range(10):
        time.sleep(1)
        print("做了2个包子！")
        c.send(i)
        c2.send(i)

producer("alex")
