基于python-tkinter写的一个定时关机的程序

很早以前写的，懒得修改，代码很简单，适合初学者
运行效果图如下：

使用注意

• 设定时间后点击开始即可实现定时关机，同时窗口也会关闭
• 想要取消关机的话，再次打开，点取消即可（有点反人类）
  代码如下

import os,time
# import multiprocessing
import threading
from tkinter import *
from tkinter import ttk
import tkinter.messagebox as message_box
window =Tk()
window.title('auto_shutdown')
window.geometry('240x180')
window.resizable(False, False)
window.update() 
var = StringVar()
var1 = StringVar()
var2 = StringVar()
# 设置func为守护线程
def funcs():
	t = threading.Thread(target=func)
	t.setDaemon(True)
	t.start()
# 执行自动关机指令
def func():
	#弹出messagebox警告提示
	message_box.showwarning("Warning", "Your pc will shutdown at %s : %s" % (var.get(),var1.get()))
	print('wohaizai')
	mytime = time.strftime('%H:%M:%S')
	h2 = mytime[0:2]
	m2 = mytime[3:5]
	s2 = mytime[6:]
	print(h2)
	print(m2)
	print(s2)
	print(var.get())
	print(var1.get())
	# 算出距离关机时间的秒数
	count_down_second=-int(h2)*3600-int(m2)*60-int(s2)+int(var.get())*3600+int(var1.get())*60+int(var2.get())
	# 如果关机设置在第二天，结果加86400（一天的总秒数)
	if count_down_second<0:
		count_down_second=count_down_second+86400
	os.system("shutdown -s -t %s" % count_down_second)
	print(count_down_second)
	window.quit()


# 快捷关机选项入口

	cb_h.current(18)
def fun_set2():
	cb_h.current(21)
def fun_set3():
	cb_h.current(22)
def fun_set4():
	cb_h.current(23)
def funcq():
	os.system('shutdown -a')
