If statement 在没有赢家的情况下，如何为井字游戏制作游戏序列？

我想展示一个标签，上面写着当没有赢家时游戏结束。我只是想做一个else声明，但是一旦有一个点击游戏就会显示出来，因为elif声明是错误的。任何想法

from tkinter import*

window = Tk()
window.title("Tic Tac Toe")
window.configure(background = "black")
window.geometry("400x400")

global clickable

ticker = 0 

#Display X or O

    global playerXturn
    if playerXturn == True :
        buttonList[c]["image"] = picX
        buttonList[c]["state"] = DISABLED
        playerXturn = False
        labelTurn ["text"] = "O's turn"

    elif clickable[c] == "" : 
        buttonList[c]["image"] = picO
        buttonList[c]["state"] = DISABLED
        playerXturn = True
        labelTurn ["text"] = "X's turn"
#Info for user
    global ticker
    ticker += 1
    if ticker == 500 :

您希望在else-if链的末尾有一个

elif

语句，用于检查是否还有剩余的空格。如果没有剩余的空格，并且在此之前的声明中没有宣布胜利者，那么一定是平局

比如：

elif (check that no empty board spaces remain) :
#print("-")
labelInfo["text"] = "It's a tie!"

---

设置一个标志来表示游戏赢了，然后设置一个单独的

if

afterwrards

if（所有动作都完成了，但没有赢）{每个人都输/平局}

你给了我一个主意，我所做的是，当一个游戏是一个时，将一个变量设置为true，然后我有一个嵌套的if语句，在9次点击后，如果变量为false，它会将标签更改为“Its a tie”。
