#解决耦合的问题
#用队列解决这种问题,起到了缓冲的作用
import threading
import time

# #python2中
# from Queue import Queue

#python3中
from queue import Queue

class Producer(threading.Thread):
    def run(self):
        global queue
        count = 0
        while True:
            if queue.qsize() < 1000:
                for i in range(100):
                    count = count +1
                    msg = '生成产品'+str(count)
                    queue.put(msg)
                    print(msg)
            time.sleep(0.5)

class Consumer(threading.Thread):
    def run(self):
        global queue
        while True:
            if queue.qsize() > 100:
                for i in range(3):
                    msg = self.name + '消费了 '+queue.get()
                    print(msg)
            time.sleep(1)

if __name__ == '__main__':
    queue = Queue()

    for i in range(500):
        queue.put('初始产品'+str(i))
    for i in range(2):
        p = Producer()
        p.start()
    for i in range(5):
        c = Consumer()
        c.start()

多看别人的代码,多问自己是否能写出来这样优雅代码!  代码一定要低耦合,高优雅!!!敲代码要多思考!
