import winsound # 导入此模块实现声音播放功能import time # 导入此模块，获取当前时间# 提示用户设置时间和分钟my_hour = input("请输入时：")my_minute = input("请输入分：")flag = 1while flag:  t = time.localtime() # 当前时间的纪元值  fmt = "%H %M"  now = time.strftime(fmt, t) # 将纪元值转化为包含时、分的字符串  now = now.split(' ') #以空格切割，将时、分放入名为now的列表中  hour = now[0]  minute = now[1]  if hour == my_hour and minute == my_minute:    music = 'Good Time.wav'    winsound.PlaySound(music, winsound.SND_ALIAS)    flag = 0
