解耦：分工，降低耦合度，每个模块都是独立的

所有的过程都让中介介质处理，这就是在解耦

队列就是中介介质

阻塞队列是一个缓冲区，平衡生产者和消费者

random.randrange(3)　随机取1或2

print('\033[32.lm。。。。.\033[Om')　加颜色

队列是用来多线程之间通信

q.task_done()　给队列发信号

q.join()　　等待信号

put,get　　q.task_done()　发信号

　　　　　q.join()　　发了信号才能接收信号，并判断队列是否为空，则执行下面的代码

import time,randomimport queue,threadingq = queue.Queue()def Producer(name):  count = 0  while count <10:    print("making........")    time.sleep(5)    q.put(count)    print('Producer %s has produced %s baozi..' %(name, count))    count +=1    #q.task_done()    q.join()    print("ok......")def Consumer(name):  count = 0  while count <10:        time.sleep(random.randrange(4))    # if not q.empty():    #     print("waiting.....")        #q.join()        data = q.get()        print("eating....")        time.sleep(4)        q.task_done()        #print(data)        print('\033[32;1mConsumer %s has eat %s baozi...\033[0m' %(name, data))    # else:    #     print("-----no baozi anymore----")        count +=1p1 = threading.Thread(target=Producer, args=('A君',))c1 = threading.Thread(target=Consumer, args=('B君',))c2 = threading.Thread(target=Consumer, args=('C君',))c3 = threading.Thread(target=Consumer, args=('D君',))p1.start()c1.start()c2.start()c3.start()
