Python 是否有其他方法可以将单击的互动程序与间隙交换？

如何在间隙平铺和单击的平铺之间进行交换？ 我下面的代码显示了单击的内容，但只要我想交换这两个内容，就会出现一个错误

最终目标是创建一个滑动益智游戏，但首先我只想交换两个瓷砖，然后我将设置一个条件，即只能单击间隙瓷砖周围的瓷砖

对不起，如果这是一个愚蠢的问题，我已经坐了2天与此代码，并开始看到双！xD

我很难理解这是如何工作的，但有一个问题；从

tile（）

创建每个磁贴时，不会保存对父（板）的引用。然后在方法

中单击（）

调用类

Board（）

，而不是实例=self.parent

class Tile(Label):
    def __init__(self, parent, image, pos):
        Label.__init__(self, parent, image=image)
        self.bind("<Button-1>", self.click)
        self.parent = parent    # Save reference to parent
        self.image = image
        self.pos = pos
        self.curPos = pos

    def click(self, event):
        self.parent.slideIt(self.pos)   # Call method on parent

    def show(self):
        self.grid(row = self.pos[0], column = self.pos[1])

此代码不会为我生成任何错误

嘿，伙计，谢谢你的回复！它的工作原理是，当我点击“开始”时，它会创建一个电路板。然后一个图像被裁剪并分为9个平铺（在createTiles中），其中一个设置为间隙平铺。它将在板上显示瓷砖。我尝试了你的解决方案，但还是遇到了同样的错误。我得到了大致的想法，但是

Tiles（）

类中有很多方法，我没有费心去理解它们。但是我对代码的修改肯定比我想象的要多，所以我在我的整个示例中都发布了。我已经将其缩短为不必每次运行时都打开文件等。现在它从电路板错误更改为：AttributeError:'NoneType'对象没有属性'pos'，非常感谢！那么我的问题到底是什么呢？这都在我的答案中；调用类而不是实例，然后提供具有错误参数的方法。
