以下借助Python函数实现一个跑秒表的实例。
代码语言：txt复制import time
class DigitClock:
"""数字时钟"""
def __init__(self):
"""初始化方法
:param hour: 时
:param minute: 分
:param second: 秒
"""
cur_time = time.localtime()
self._hour = cur_time.tm_hour
self._minute = cur_time.tm_min
self._second = cur_time.tm_sec
def run(self):
"""时钟行走方法"""
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 f"{self._hour}:{self._minute}:{self._second}"
def main():
myclock = DigitClock()
# 走10步自动停止
steps = 5
for _ in range(steps):
print(myclock.show())
time.sleep(1)
myclock.run()
main()
运行结果如下：
14:29:1
14:29:2
14:29:3
14:29:4
14:29:5
