多线程应用-类（thread）

在对class thread加锁时，锁无法正常应用，函数方式没问题。

在使用class thread方法时，并发后的查询结果不对，函数方式没问题。

# -*- coding: UTF-8 -*-
from time import ctime,sleep
import threading,datetime
from Queue import Queue

class pdc(threading.Thread):
    def __init__(self,t_name):
        threading.Thread.__init__(self,name=t_name)
        #self.name='aaa' #此时self还不是Thread，为string格式
    def run(self): #run()方法继承于threading，需要重写定义自己的内容
        self.setName('b'+str(i)) #self.setName('bbb') #此时self是Thread，可以通过 print dir(self) 查看所具有的属性/方法
        print '%s: %s is producing %d to the queue.' %(ctime(),self.getName(),i)
        sleep(1)

if __name__ == '__main__':

生产者消费者模型，直接将queue定义为global，实际同上：

from time import ctime,sleep
import threading,datetime
from Queue import Queue
global queue 

class pdc(threading.Thread):
    def __init__(self,queue):
        threading.Thread.__init__(self)

        for i in range(5):

            print '%s: producing %s to the queue.' %(ctime(),nn)
            queue.put(nn) #将生成出来的数据放入到queue中
            sleep(0.1)
        print '%s pdc finished!' %(ctime())

class cum(threading.Thread):
    def __init__(self,queue):
        threading.Thread.__init__(self)

    def run(self):
        for i in range(5):
            val = queue.get() #从queue中取数据进行消费
            print '%s: consuming %s. the last number of queue is %d' %(ctime(),val,queue.qsize())
            sleep(1)
        print '%s consume finished!' %(ctime())

if __name__ == '__main__':
    queue = Queue()
    producer = pdc(queue)
    consumer = cum(queue)
    producer.start()
    consumer.start()
    producer.join()
