开启线程的两种方式

方式一、

from threading import Thread
import time


# 开启线程的两种方式之一、

def task(name):
    print('%s is run' % name)
    time.sleep(1)
    print('over')


if __name__ == '__main__':
    p = Thread(target=task, args=('egon',))
    p.start()
    print('主线程')  # 其实线程本没有主次之分

　　方式二、

class MyThread(Thread):
    def __init__(self, name):
        super().__init__()
        self.name = name
    
    def run(self):
        print('%s is running' % self.name)
        time.sleep(1)
        print('%s is done' % self.name)


if __name__ == '__main__':
    t1 = MyThread('qzk')
    t1.start()
    print('主线程')
