案例1
#实现多选Checkbutton
from tkinter import *
root = Tk()
GIRLS = ['西施','貂蝉','王昭君','杨玉环']
v = []
for girl in GIRLS:
v.append(IntVar())
b = Checkbutton(root,text = girl, variable = v[-1])
b.pack(anchor = W)
mainloop()
类的形式
#实现多选Checkbutton
from tkinter import *
import math as m
class App(Frame):
def __init__(self,master = None):
Frame.__init__(self,master)
self.pack()
# create the applilcation

#
# here are method calls to the window manger class
#
myapp.master.title("Checkbutton")

案例2
- for实现循环选择
import tkinter as tk
window=tk.Tk()
window.title('checkbutton')
window.geometry('400x400')
#定义label用于显示
l=tk.Label(window,
bg='red',
width=40,height=2,
text='u have not chosen anything yet')
l.pack()
def print_selection():
if (op_mark[0].get()==1)&(op_mark[1].get()==1):
l.config(text='你怎么两个人通吃啊！')
elif(op_mark[0].get()==1)&(op_mark[1].get()==0):

elif(op_mark[0].get()==0)&(op_mark[1].get()==1):

op_mark=[tk.IntVar(),tk.IntVar()]
#这里注意onvalue和offvalue不能改名字，只能用这两个名字！我就被坑了。。
