PYTHON线程知识再研习B

使用threading.Thread模块，也有两种使用方法，可以用类，也可以在实例化对象中传入函数或类实例。

from threading import Thread
import time

def run_thread(n):
    for i in range(n):
        print i

class race(Thread):
    def __init__(self,threadname,interval):
        Thread.__init__(self,name=threadname)
        self.interval = interval
        self.isrunning = True

    def run(self):
        while self.isrunning:
            print ‘thread %s is running,time:%s\n‘ %(self.getName(),time.ctime())
            time.sleep(self.interval)
    def stop(self):
        self.isrunning = False

def test():
    t1 = Thread(target=run_thread,args=(5,))
    t1.start()

    thread1 = race(‘A‘,1)
    thread2 = race(‘B‘,2)
    thread1.start()
    thread2.start()
    time.sleep(4)
    thread1.stop()
    thread2.stop()

if __name__ == ‘__main__‘:
    test()
