some tips about python Six

import tkinter as tk #引入模块

window = tk.Tk() #设置window对象

window.title('my window')

window.geometry('200x200')

l = tk.Label(window,bg = 'yellow',width = 22,text = 'empty')#设置Label对象，宽度是22个字体

l.pack()#显示在window上

def print_selection():#设置函数

        if(var1.get() == 1) & (var2.get() == 0):#进行判断

                l.config(text = 'I love only Python')#对Label对象的text参数进行设置

        elif(var1.get() == 0) & (var2.get() == 1):

                l.config(text = 'I love only C++')

        elif(var1.get() == 0) & (var2.get() == 0):

                l.config(text = 'I do not love either')

        else:

                l.config(text = 'I love both')

var1 = tk.IntVar()#设置tkinter的整型变量

var2 = tk.IntVar()

c1 = tk.Checkbutton(window,text = 'Python',variable = var1,onvalue = 1, offvalue = 0,

                    command = print_selection)#设置tkinter的复选框，设置变量var1，并且选择var1的时候值为1，不选择的时候值为0

c2 = tk.Checkbutton(window,text = 'C++',variable = var2, onvalue = 1, offvalue = 0,

                    command = print_selection)

c1.pack()

c2.pack()

window.mainloop()#window主循环
