# 通过继承Thred类创建线程

# 线程1
class Mythread(threading.Thread):
    def run(self):  # 类里面必须定义一个run方法，当调用start方法时，会自动运行run方法，run里面的代码就是要执行的子线程
        self.test1()

    def test1(self):
        for i in range(3):
            print(‘我是线程1‘)
            time.sleep(1)

# 线程2
class Mythread1(threading.Thread):
        def run(self):
            self.test2()
            
        def test2(self):
            for i in range(3):
                print(‘我是线程2‘)
                time.sleep(1)


if __name__ == ‘__main__‘:
    t = Mythread()
    t1 = Mythread1()
    t.start()
    t1.start()
