如何在网格中显示图像的缩略图，然后使用tkinter和python在新窗口中打开一个图像？

更新：找到解决方案并更新为自我回答。

我在一个目录中有20个jpg图像。使用Python 3.7+Tkinter 8.6.10。我访问它们，调整大小并将它们显示在网格中的主窗口中。网格有12行x 5列=60帧。 第1行中的所有帧都有标签，标签中填充了大小调整后的图像。 第2行中的所有框架都有带有文本“放大”的标签。 第3行中的所有框架都有带有文本“Select”的标签。 这种模式重复

单击“放大”按钮，我想在新窗口中显示完整的未调整大小的图像。我在显示放大图像时遇到了一个问题。将打开一个新窗口，但没有图像。我在控制台中遇到以下错误： --------------------控制台输出开始--------------------

请帮助。

有几件事我在概念上还没有弄清楚，还有一些其他错误：如何和为什么使用顶级窗口与根窗口；如何将参数传递给按钮调用的函数；在某些地方指定窗口标题的愚蠢错误

如果对任何人都有帮助，请在此处将完整的清理代码上载到github:

这是因为您使用了多个

Tk（）

实例。使用

Toplevel（）

代替

do\u放大\u btn\u按功能（）

。谢谢。顺便说一句，我刚刚破解了它。我在理解上有几个差距。发布工作和清洁代码作为答案。
