Tkinter 按钮 function 无法按预期工作

Question

我在做什么：

我正在 Tkinter 中编写“Rock, Paper, Scissors”游戏。 我现在所做的是，我正在编写一个 function（或 2 个），除了被按下的按钮之外，它会取消网格按钮。 到目前为止，该部分正在工作，但我也希望它们在再次单击同一个按钮时重新出现。

该代码不会引发任何类型的错误。 只是在再次单击所选按钮时不会重新放置按钮。

任何帮助是极大的赞赏！

编码：

        # set title of the file to the value of 'window_name';

Answer 1

在您的button_click function 中，在 for 循环中应该是

if button != self:
    button.is_removed = True
    button.master.grid_forget()

而不是self.is_removed = True 。 让我知道它是否有效。
