我正在尝试使用tkinter制作tic-tac-toe，我正在列表中存储播放器和计算机输入，并使用它们检查输入位置是否已被占用。但是，它不起作用，在第二次转动后，禁用的按钮变为正常，尽管它们已经被标记。那么，有人能指出代码的哪一部分将按钮返回到正常状态吗。

from tkinter import *

root = Tk()
root.title("Tic Tac Toe")
root.geometry("400x400")

global computerletter
playerletter = "X"
computerletter = "O"
x = 50
y = 50

computerList = []
