python封装对象实现时间效果

本文实例为大家分享了python封装对象实现时间效果的具体代码，供大家参考，具体内容如下

# 钟表
import time
class Clock():
 def __init__(self, hour, minute, second):  # 时 分 秒
   self.hour = hour
   self.minute = minute
   self.second = second
 @classmethod
 def now(cls):
   nowtime = time.localtime()
   return cls(nowtime.tm_hour, nowtime.tm_min, nowtime.tm_sec)
 def run(self):
   self.second += 1
   if self.second == 60:
     self.second = 0
     self.minute += 1
     if self.minute == 60:
       self.minute = 0
       self.hour += 1
       if self.hour == 24:
         self.hour = 0
 def show(self):
   return "{} : {} : {}".format(self.hour, self.minute, self.second)

if __name__ == '__main__':
   cl = Clock.now()
   while True:
     print(cl.show())
     time.sleep(1)
     cl.run()
