yield实现异步

def cash_out(amount):
while amount >0:
        amount-=1
 yield 1
 print('get again %s' %amount)
atm=cash_out(5)
print(type(atm))
print(atm.next())
print(234234)
print(atm.next())

import time
def consumer(name):
print("%s 准备吃包子啦!" %name)
while 1:
 baozi = yield
 print("包子[%s]来了，被[%s]吃了!" %(baozi, name))

def producer():
 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()
