如何获取按钮列表中特定按钮的文本？我正在使用Tkinter

Question

我目前正在制作一个Tic-Tac-Toe游戏，并且我正在努力检查是否有人获得了连续3件作品，所以我可以告诉他们他们已经赢了。我试图通过检查按钮的文本来做到这一点，看看我是否已经连续3次。但是，我不知道如何检查列表中特定按钮的文本。有没有人有任何想法，或者如果有更好的方法，你能让我知道吗？

      self.play_again.grid(row=6, column=1, columnspan=3) 

    def new_game(self): 
     self.turn = 0 



game = TicTacToe() 
game.mainloop() 

部分我与

for x in range(0,8): 
      if self.game_buttons[x] == "[X]" and self.game_buttons[(x+3)%9]: 
       if self.game_buttons[(x+6)%9] == "[X]": 
        print("Winner") 

我在这部分我没有找到文字实现挣扎，但我真的不知道该怎么对双方调用具体的清单项目和文字。

调用包含tkinter Button小部件的list中的元素将返回小部件本身，就像调用存储在list元素中的任何其他值一样。这意味着如果你想要text属性值的元素，你可以使用["text"]或.cget("text")。

下面参见：

from tkinter import * 

root = Tk() 

array = [Button(root, text="1"), Button(root, text="2"), Button(root, text="3")] 

for i in array: 
    print(type(i)) 
    print(i.cget("text")) 
    print(i["text"])
