我先说我注释掉了self.start_game()行，因为start_game方法不存在。我还要补充一点，为了重现这个问题，我启动了这个应用程序，然后选择了在没有任何数量玩家的情况下开始游戏。在

最终你可以做你想做的事情：也就是说，不要总是按“绘制”按钮。我要做的是在__init__（）内的某处添加self.button_draw = None行。这样可以确保窗口始终具有一个button_draw属性，从而消除了关于该属性的AttributeError。在

下一步，您需要调整if中较低的if语句，以便从网格中删除已创建的“Draw”按钮：

        if self.type_partie.get() == "with draw":
            self.button_draw = Button(self, text="Draw", command=self.button_to_draw)
            self.button_draw.grid(row=3, column=0)
        elif self.button_draw is not None:
            self.button_draw.grid_remove()
            self.button_draw.destroy()
            self.button_draw = None

我用else替换了elif，并且self.button_draw不是{}的条件：如果没有按钮可以删除，我们就不能删除'Draw'按钮。在

还请注意，我将self.destroy替换为self.button_draw.destroy()：如果你调用了这个方法，前者会关闭你的应用程序，但是由于你没有调用self.desroy，它什么也没有做。此外，一旦按钮被破坏，我们可以将self.button_draw设置回None，以表示我们没有“绘制”按钮。在

类似地，如果“Draw”按钮存在并且你用Draw开始另一个游戏，你的窗口中会有两个按钮。你只能看到一个，因为一个在另一个上面。但是，由于您只保留对一个按钮的引用，因此只能删除这两个按钮中的一个。如果按钮不存在，我将留给您对代码进行类似的修改，以便只添加按钮。在
