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()
