我希望用户点击数字，然后数字应该改变颜色，我将能够捕获用户点击的标签，然后该表格将以文本和PDF格式保存。提前感谢mil提供任何帮助

以下是您可以在下面添加的代码＆＃34; f1_l1.grid（row = 0，column = 6）＆＃34;线（约77）。但我认为您可能需要RadioButton用于此目的，因为它会自动取消标记其他选项并支持IntVar。有关活动的更多信息：http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/events.html此网页包含优秀（但有点过时）的文档。
顺便说一句，在为自己制作程序时，您可能需要应用一个快速修复程序。在Python中，您可以在类及其定义之外的类中添加字段。例如。在你的代码中，你感冒后写了f1_l1.myNumber = 1＆＃34;创建＆＃34;它和clickFunction而不是grid_info（）使用selectedNumber = event.widget.myNumber。它做了这件事，但是不要告诉他们我教过你;）因为它不被认为是以这种方式添加字段的良好做法。
如果您有任何其他问题，请随时提出。
