为了在家安心学习，我决定写一段代码播放上课的铃声。
之前中学时就希望有一个这样的软件，周末就可以高效学习了。
但是网上搜不到相关软件，当时也不会写代码，就用闹钟来代替了。
现在自己写一个试试。
原本我是用C++写的，但后来发现C++太麻烦了。
要用到其他的库，那些库也不好安装，总是有一大堆难以解决的报错，就换Python了。
没想到Python这么方便。
功能一、播放音频
安装playsound库即可运行
from playsound import playsound
playsound('1.wav')
功能二、获取系统时间
import time
def main():
print(time.localtime())
year = time.localtime().tm_year
month = time.localtime().tm_mon
day = time.localtime().tm_mday
hour = time.localtime().tm_hour
minute = time.localtime().tm_min
second = time.localtime().tm_sec
print(year, '年', month, '月', day, '日')
print(hour, '时', minute, '分', second, '秒')
main()
功能三、上课铃声的定时播放
from playsound import playsound
import time
def ring():
playsound('1.wav')
time.sleep(5)
playsound('1.wav')
time.sleep(60)
def timeoff(hour,minute):
if hour == time.localtime().tm_hour and minute == time.localtime().tm_min:
ring()
while 1:
timeoff(8,0)
timeoff(8,45)
timeoff(8,50)
timeoff(9,35)
timeoff(9,50)
timeoff(10,35)
timeoff(10,40)
timeoff(11,25)
timeoff(11,30)
timeoff(12,15)
timeoff(13,30)
timeoff(14,15)
timeoff(14,20)
timeoff(15,20)
timeoff(16,5)
timeoff(16,10)
timeoff(16,55)
timeoff(18,30)
timeoff(19,15)
timeoff(19,20)
timeoff(20,5)
timeoff(20,10)
timeoff(20,55)
注释：
原本连续循环播放一分钟，效果不理想，利用了sleep语句使代码休眠，可以巧妙地解决这个问题
但是仍然存在CPU占用率过高的问题
上课时间表
编译
编译后再使用，就很方便了
优化一 针对CPU占用率过高的优化
原代码用了一个while(1)的循环
每一帧都在刷新比对系统时间，这使得CPU占用率过高
要求精确到分钟，那么现在我们每60秒检查一次时间，就可大大降低CPU占用率
from playsound import playsound

def ring():
global status
status=status+1
if status%2==0:
print("当前时间:",time.localtime().tm_hour,"时",time.localtime().tm_min,"分，","状态:下课")
else:

time.sleep(60)#每60秒检查一次
优化二 改变时间表的数据类型
使用字典、元组存储打铃时间和上下课状态
使代码更符合使用逻辑、运行时的漏洞更少

效果
打开软件时，自适应休眠
倒计时一分钟时，休眠结束，每5秒刷新一次
时间到了，打铃
打铃结束，进入休眠
