好吧，我正在用Python和Tkinter制作一个计算器，它正在工作，但是我想添加一个'语言'选项，你可以在这里更改程序的语言，我想知道如何重命名add_comand标签。 ..
以及如何删除将级联转换为窗口的选项？ “------”选项？
最后，当你点击时，我需要做什么来在级联选项的侧面出现'已检查'图标？
CODE：
from tkinter import *
from math import *
n1=0
op=""
n2=0
dt=False
col=False

lb["text"]+=str(n)
def operation(o):

if dt==False:

elif dt==True:
n1=float(lb["text"])
