在Python中，如何检查按钮列表中单击了哪个按钮？

Question

我正在尝试查看我在程序中单击了哪个按钮，然后单独更新该按钮上的文本。如何找到点击的按钮？该程序是一个tictactoe游戏，我需要在我点击的位置放置一个X.代码如下：

 #sets up the buttons
    for i in range(1,10):
        self.button = tk.Button(mainWindow, width=30, height=14, bg="white", text="",command=self.Click)
        listOfButtons.append(self.button)

    for button in listOfButtons:
        """
        Grids each button dynamically with the specified row and column. each time through the loop it will 
        increase the column by 1 until it gets to 3. When columnNum == 4, it will reset it to 1 and add 1 to the 
        row. 
        """
        button.grid(row=rowNum, column=columnNum)
        columnNum += 1
        if(columnNum == 4):
            rowNum += 1
            columnNum = 1


def Click(self):
    #Button command init
    for button in listOfButtons:
