Python 多线程-线程的继承

自定义类，继承 Thread，重写 run()方法

　　

import threading
import time

class MyThread(threading.Thread):
    def __init__(self,thread_name):
        threading.Thread.__init__(self)
        self.thread_name=thread_name

    """重写run方法"""
    def run(self):
        time.sleep(3)
        print(self.thread_name)

if __name__ == '__main__':
    t1 = MyThread('thread_1')
    t2 = MyThread('thread_2')


    t1.start()
    t2.start()
