python实现生产者和消费者模式

利用python的线程实现简单生产者和消费者模式，这种模式在多线程编程时还是用的比较多吧，下面是源代码：

#!/usr/bin/python
# -*- coding: utf-8 -*-
import requests,time
import threading,queue


class mythread_1(threading.Thread):
    def __init__(self,queue):
        super(mythread_1,self).__init__()
        self.queue = queue
    def run(self):
        try:
            for i in range(5):
                products = 'http://www.mzitu.com/xinggan/page/'+str(i)
                self.queue.put(products)
                time.sleep(1)
            print(self.getName(),'shengcan finish')
        except:
            print('field')
        finally:
            print('ok')

class mythread_2(threading.Thread):
    def __init__(self,queue):
        super(mythread_2,self).__init__()
        self.queue = queue

    def run(self):
        try:
            for i in range(5):
                url = self.queue.get()
                reponse = requests.get(url)
                print(reponse.status_code)
                time.sleep(1)
            print(self.getName(),'xiaofei finish')
        except:
            print('field')
        finally:
            print('ok')
def main():
    q = queue.Queue()
    t1 = mythread_1(q)
    t2 = mythread_2(q)
    t1.start()
    t2.start()

    t1.join()
    t2.join()
