Day08 - 面向对象编程基础 定义一个类描述数字时钟

定义一个类描述数字时钟
未import time模块导致出错
from time import sleep
class Clock(object):
"""数字时钟"""

def __init__(self, hour=0, minute=0, second=0):
    """初始化方法

    :param hour: 时
    :param minute: 分
    :param second: 秒
    """
    self._hour = hour
    self._minute = minute
    self._second = second

def run(self):
    """走字"""
    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):
    """显示时间"""
    return '%02d:%02d:%02d' % \
           (self._hour, self._minute, self._second)

def main():
clock = Clock(23, 59, 58)
while True:
print(clock.show())
sleep(1)
clock.run()

if name == 'main':
main()

Start with the clock example in the issue body and its main() entry point; verify the time import used by sleep is available when the script runs. Done means the example starts without an import error and the clock continues to display advancing time.
