我觉得Window8有一个重大的优点就是支持休眠的功能，休眠以后再次开机可以保持原来已经打开的窗口。但是我发现我的电脑休眠以后会自己开机，也不知道怎么回事，于是我想可以利用python来实现在固定时间内自动关机或者休眠的功能。主要的思路如下：

获取当前时间->与设定的时间作比较->超出了设定时间->关机或休眠

代码如下：

#coding=utf-8import time, os ,threadingclass TimeCmp:    def __init__(self, TimeStart, TimeEnd):        self.TimeStart=TimeStart        self.TimeEnd=TimeEnd    def GetNowTime(self):        pass        #now = time.strftime("%Y-%m-%d %H:%M:%S")    def Cmp(self):        LocalTime=time.localtime(time.time())        self.__TimeNow_1=LocalTime.tm_hour*3600+LocalTime.tm_min*60+LocalTime.tm_sec        self.__TimeStart_1=3600*self.TimeStart[0]+60*self.TimeStart[1]+self.TimeStart[2]        self.__TimeEnd_1=3600*self.TimeEnd[0]+60*self.TimeEnd[1]+self.TimeEnd[2]        #print 'self.__TimeNow_1',self.__TimeNow_1        #print 'self.__TimeStart_1',self.__TimeStart_1        #print 'self.__TimeEnd_1',self.__TimeEnd_1        if self.__TimeNow_1 > self.__TimeStart_1 and self.__TimeNow_1 < self.__TimeEnd_1:            return True        else:            return Falsedef run():    TimeStart=(8,0,0)    TimeEnd=(23,30,00)    SystemCmd='rundll32 powrprof.dll,SetSuspendState -t -s 60'    #SystemCmd='shutdown -r'    while True:        TimeCmpResult=TimeCmp(TimeStart, TimeEnd)        #print TimeCmpResult.Cmp()        shutdown=not TimeCmpResult.Cmp()        if shutdown:            print "Computer will be off"            time.sleep(float(60))            os.system(SystemCmd)        else:            print "Computer is on"            pass        time.sleep(float(600))if __name__=="__main__":    run()

也可以做成Windows服务实现自动启动，见
