python 调用windows api查看系统的电量，pythonapi,通过调用GetSyste

通过调用GetSystemPowerStatus Windows Api来判断AC Power是开启还是关闭状态。是一个python调用windows api的例子。

import osimport win32conimport sysimport timefrom ctypes import *class PowerClass(Structure):    _fields_ = [('ACLineStatus', c_byte),            ('BatteryFlag', c_byte),            ('BatteryLifePercent', c_byte),            ('Reserved1',c_byte),            ('BatteryLifeTime',c_ulong),            ('BatteryFullLifeTime',c_ulong)]powerclass = PowerClass()while True:    result = windll.kernel32.GetSystemPowerStatus( byref(powerclass) )    try:        state = int(powerclass.ACLineStatus)    except:        state = 0     if state == 1:        print 'Power is on...'    else:        print 'Power is off...\a'  #\a = bell sounds beep on computer    print 'Sleeping for 5 seconds...'    time.sleep(5)
