python 调用windows api查看系统的电量详解编程语言

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 os 
import win32con 
import sys 
import time 
from 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)
