当单击任何其他CheckButton时，如何禁用和检查一个CheckButton。

我想在将chk1设置为“已检查”时也将chk2设置为“已检查，如果我未选中，我希望将chk1的状态设置为正常。”>

我在使用以下命令时遇到错误-

import tkinter as tk
from tkinter import ttk

class Root(tk.Tk):
    def __init__(self):
        super().__init__()

        var1 = tk.IntVar()
        chk1 = ttk.Checkbutton(self, text = 'Class', variable = var1)
        #chk1.state(['selected'])
        chk1.pack(side = 'left')
        var2 = tk.IntVar()
        chk2 = ttk.Checkbutton(self, text = 'Section', variable = var2,
        command = lambda: self.chk(chk1, var2))
        #chk2.state(['selected'])
        chk2.pack(side = 'left')

    def chk(self, obj, self_val):
        if self_val.get() == 1: #changed from 0 to 1
            obj.state['selected']
            obj.configure(state = 'disabled')
        else:
            obj.configure(state = 'normal')

if __name__ == '__main__':
    Root().mainloop()
Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\Sagar\Anaconda3\lib\tkinter\__init__.py", line 1705, in __call__
    return self.func(*args)
  File "d:\chkbtn.py", line 18, in <lambda>
    command = lambda: self.chk(chk1, var2))
  File "d:\chkbtn.py", line 24, in chk
    obj.state['selected']

我认为经过一番困惑之后，您需要在lambda和方法中添加第三个变量。
