Tkinter图像记忆游戏点击按钮不显示图像问题求助

使用Python的Tkinter库开发自定义图像记忆游戏时，按钮默认白色背景图正常显示，但点击按钮后无法切换到目标图像。用数字替代图像时功能正常，确定问题出在图像相关逻辑上。

核心问题有两个：

1. 图像对象比较逻辑错误：b["image"] == base 的比较方式不成立，因为Tkinter中Button["image"]返回的是图像对象的内部字符串标识，而非直接的ImageTk.PhotoImage对象，无法与base对象直接匹配。
2. 代码缩进错误：匹配成功分支中的变量重置语句缩进错误，导致逻辑无法正常执行。

• 给每个按钮添加自定义属性current_image，用于跟踪当前显示的图像对象，替代直接比较b["image"]的方式。
• 修正匹配成功分支的缩进问题，确保变量重置逻辑正确执行。
