使用Threading模块创建线程

使用Threading模块创建线程，直接从threading.Thread继承，然后重写__init__方法和run方法：

实例(Python 2.0+)

#!/usr/bin/python# -*- coding: UTF-8 -*- import threadingimport time exitFlag = 0 class myThread (threading.Thread): #继承父类threading.Thread def __init__(self, threadID, name, counter): threading.Thread.__init__(self) self.threadID = threadID self.name = name self.counter = counter def run(self): #把要执行的代码写到run函数里面 线程在创建后会直接运行run函数 print "Starting " + self.name print_time(self.name, self.counter, 5) print "Exiting " + self.name def print_time(threadName, delay, counter): while counter: if exitFlag: (threading.Thread).exit() time.sleep(delay) print "%s: %s" % (threadName, time.ctime(time.time())) counter -= 1 # 创建新线程thread1 = myThread(1, "Thread-1", 1)thread2 = myThread(2, "Thread-2", 2) # 开启线程thread1.start()thread2.start() print "Exiting Main Thread"
