简单的计数器

import time
import datetime
class TimeClass(object):
    name = "time"
    def time(self,hour,min,sec):
        # 获取两个当前时间，然后格式化时间
        time1 = datetime.datetime.now()
        time2 = datetime.datetime.now()
        time3 = time2 - time1
        # 将传递的时间参数相加
        time4=time3 + datetime.timedelta(hours=hour) + datetime.timedelta(minutes=min) + datetime.timedelta(seconds=sec)
        # 循环加一秒
        while True:
            time4 += datetime.timedelta(seconds=1)
            time.sleep(1)
            time4 += datetime.timedelta(days=0)
            print(time4)


cc = TimeClass()
cc.time(22,22,22)

结果如下
