天天面对着电脑敲代码，你是否忘记了保护视力了，眼睛的度数在上涨，镜片变厚，这是我们期望的么？今天有点空闲时间，写了个Python自动锁屏脚本，使用的是Python 2.7,代码如下

#coding:utf8



import os

import time



#locktime你设置的锁屏周期(单位 ： s)

locktime = 1 * 60 * 60

starttime = int(time.time())



def locakMonitor():
os.system('RunDll32.exe user32.dll,LockWorkStation')



def showWindowMsg(info,btnval,wintitle):
vbstrcommand = 'mshta vbscript:msgbox('+'"'+info+'"'+","+str(btnval) +","+'"'+wintitle+'"'+")(window.close)"
#print vbstrcommand
os.system(vbstrcommand)



def getInput():
while True:
	input = raw_input('continue lock(y or n):')
	lowerinput = input.lower()
	if 'y' == lowerinput:
		return True
	elif 'n' == lowerinput:
		return False
	else:
		print u'输入错误'
		continue



if __name__ == '__main__':
while True:
	nowtime = int(time.time())
	time.sleep(1)
	#os.system("mshta vbscript:msgbox("+"cccc" +",64,"+"ccccc"+")(window.close)");
	print 'after ' + str(nowtime - starttime) + 's'
	if(nowtime == starttime + locktime):
		showWindowMsg('lock after 5s',0,'lockinfo')
		print u'5秒后将锁屏，请注意保护视力....'
		time.sleep(5)
		locakMonitor()
		if getInput() == True:
			starttime = int(time.time())
			continue
		else:
			print u'锁屏脚本结束'
			break
		#重置开始时间
		starttime = int(time.time())

可以自己去设定锁屏周期，运行下脚本，自动锁屏

修改部分拼写错误，锁屏时间计算问题，窗口弹出不显示，直接发出声音

version2.0 如下

#coding:utf8



import os

import time

import winsound

import webbrowser

 

#locktime你设置的锁屏周期(单位 ： s)

locktime = 1 * 15

starttime = int(time.time())



def lockMonitor():
os.system('RunDll32.exe user32.dll,LockWorkStation')

 

def showWindowMsg(info,btnval,wintitle):
vbstrcommand = 'mshta vbscript:msgbox('+'"'+info+'"'+","+str(btnval) +","+'"'+wintitle+'"'+")(window.close)"
#print vbstrcommand
os.system(vbstrcommand)

 

def getInput():
while True:
	input = raw_input('continue lock(y or n):')
	lowerinput = input.lower()
	if 'y' == lowerinput:
		return True
	elif 'n' == lowerinput:
		return False
	else:
		print u'输入错误'
		continue

 

if __name__ == '__main__':
while True:
	time.sleep(1)
	nowtime = int(time.time())
	#os.system("mshta vbscript:msgbox("+"cccc" +",64,"+"ccccc"+")(window.close)");
	print 'running ' + str(nowtime - starttime) + 's'
	if nowtime >= (starttime + locktime):
		#窗口显示看不到，发出声音
		#showWindowMsg('lock after 5s',0,'lockinfo')
		print u'5秒后将锁屏，请注意保护视力....'
		winsound.Beep(600,5000)
		#webbrowser.open('C:/Users/chengdu/Desktop/FILE/1.html')
		#time.sleep(5)
		lockMonitor()
		if getInput() == True:
			starttime = int(time.time())
			continue
		else:
			print u'锁屏脚本结束'
			break

Python3版本

#coding:utf8



import os

import time

import winsound

import webbrowser

 

#locktime你设置的锁屏周期(单位 ： s)

locktime = 1 * 15

starttime = int(time.time())



def lockMonitor():
os.system('RunDll32.exe user32.dll,LockWorkStation')

 

def showWindowMsg(info,btnval,wintitle):
vbstrcommand = 'mshta vbscript:msgbox('+'"'+info+'"'+","+str(btnval) +","+'"'+wintitle+'"'+")(window.close)"
#print vbstrcommand
os.system(vbstrcommand)

 

def getInput():
while True:
	kinput = input('continue running(y or n):')
	lowerinput = kinput.lower()
	if 'y' == lowerinput:
		return True
	elif 'n' == lowerinput:
		return False
	else:
		print (u'输入错误')
		continue

 

if __name__ == '__main__':
while True:
	time.sleep(1)
	nowtime = int(time.time())
	#os.system("mshta vbscript:msgbox("+"cccc" +",64,"+"ccccc"+")(window.close)");
	print ('running ' + str(nowtime - starttime) + 's')
	if nowtime >= (starttime + locktime):
		#窗口显示看不到，发出声音
		#showWindowMsg('lock after 5s',0,'lockinfo')
		print (u'5秒后将锁屏，请注意保护视力....')
		winsound.Beep(600,5000)
		#webbrowser.open('C:/Users/chengdu/Desktop/FILE/1.html')
		#time.sleep(5)
		lockMonitor()
		if getInput() == True:
			starttime = int(time.time())
			continue
		else:
			print (u'锁屏脚本结束')
			break
