第十七节 创建线程类

import threading
import time


class write_a(threading.Thread):
    def run(self):
        for x in range(3):
            print("写字%s" % threading.current_thread())
            time.sleep(1)


class draw(threading.Thread):
    def run(self):
        for x in range(3):
            print("画画%s" % threading.current_thread())
            time.sleep(1)


def main():
    t1 = write_a()
    t2 = draw()
    t1.start()
    t2.start()

if __name__ == '__main__':
    main()
