Python--day38---进程间通信--初识队列（multiprocess.Queue）之生产者，消费者模型

1，生产者消费者模型.py

 import random
 import time
 from multiprocessing import Queue, Process

 def producer(name,food,q):
     for i in range(4):
         time.sleep(random.randint(1,3))
         f = '%s生产了%s%s'%(name,food,i)
         print(f)
         q.put(f)

 def consumer(q,name):
     while True:
         food = q.get()
         if food is None:
             print('%s获取到了一个空',name)
             break
         print('\033[31m%s消费了%s\033[0m' %(name,food))
         time.sleep(random.randint(1,3))

 if __name__ == '__main__':
     q = Queue(20)
     p1 = Process(target=producer,args=('Egon','包子',q))
     p2 = Process(target=producer,args=('wusir','泔水',q))
     c1 = Process(target=consumer,args=(q,'alex'))
     c2 = Process(target=consumer,args=(q,'jinboss'))
     p1.start()
     p2.start()
     c1.start()
     c2.start()
     p1.join()
     p2.join()
     q.put(None)
