python,通过创建类实现多线程例子

Posted 2021-03-23 Iceberg_710815

import threading,time
class MyThread(threading.Thread):
    def __init__(self,num):
        threading.Thread.__init__(self)
        self.num = num
    def run(self):
        print("running on number:%s"%self.num)
        time.sleep(self.num)

if __name__ == ‘__main__‘:
    begin = time.time()
    t1 = MyThread(1)
    t2 = MyThread(2)
    t1.start()
    t2.start()
    t1.join()
    t2.join()
    end = time.time()
    print(end - begin)

程序执行结果:

running on number:1
running on number:2
2.0025267601013184

Process finished with exit code 0

t.start()方法自动调用类中的run()方法,所以在实现的时候只需要将自己的任务代码写在run()方法中即可.
