我在删除Tkinter中的按钮时遇到问题

Question

我开始为学校编写此代码，不要质疑我正在学习的标签，但是我无法隐藏销毁或移除按钮以使tkinter看起来更好一些，但即使在寻找其他人来帮助后我还是失败了

from tkinter import *
import tkinter as tk
root = tk.Tk()

def toggleapps():
    ABC = Button(root, text="Alphabet Test", command=AlphabetTest)
    Dog = Button(root, text="Dog Years Calculator", command=DogYear)
    if ToggleApps.config('relief')[-1] == 'sunken':
        ToggleApps.config(relief="raised")
        #the problem
        Dog.destroy()
        ABC.destroy()
    else:
        ToggleApps.config(relief="sunken")
        Dog.grid(row=1, column=0)
        ABC.grid(row=1, column=1)

ToggleApps = Button(root, text="Apps:", width=12, relief="raised", command=toggleapps)
ToggleApps.grid(row=0, column=0)
