天天面對著電腦敲程式碼，你是否忘記了保護視力了，眼睛的度數在上漲，鏡片變厚，這是我們期望的麼？今天有點空閒時間，寫了個Python自動鎖屏指令碼，使用的是Python 2.7,程式碼如下

#coding:utf8

import os
import time

#locktime你設定的鎖屏週期(單位 ： 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'輸入錯誤'
			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秒後將鎖屏，請注意保護視力....'
			time.sleep(5)
			locakMonitor()
			if getInput() == True:
				starttime = int(time.time())
				continue
			else:
				print u'鎖屏指令碼結束'
				break
			#重置開始時間
			starttime = int(time.time())
 

  可以自己去設定鎖屏週期，執行下指令碼，自動鎖屏

   修改部分拼寫錯誤，鎖屏時間計算問題，視窗彈出不顯示，直接發出聲音

   version2.0 如下

#coding:utf8

import os
import time
import winsound
import webbrowser
 
#locktime你設定的鎖屏週期(單位 ： 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'輸入錯誤'
			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):
			#視窗顯示看不到，發出聲音
			#showWindowMsg('lock after 5s',0,'lockinfo')
			print u'5秒後將鎖屏，請注意保護視力....'
			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'鎖屏指令碼結束'
				break


 

 Python3版本

#coding:utf8

import winsound
import webbrowser
 
#locktime你設定的鎖屏週期(單位 ： s)
locktime = 1 * 15
starttime = int(time.time())

	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'輸入錯誤')
			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):
			#視窗顯示看不到，發出聲音
			#showWindowMsg('lock after 5s',0,'lockinfo')
			print (u'5秒後將鎖屏，請注意保護視力....')
			winsound.Beep(600,5000)
			#webbrowser.open('C:/Users/chengdu/Desktop/FILE/1.html')
			#time.sleep(5)
			lockMonitor()
			if getInput() == True:
