Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python38\lib\tkinter\__init__.py", line 1883, in __call__

    death_cases = str(df.values['Total Cases'][lb2.cget('text')])
IndexError: only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or 
boolean arrays are valid indices

对不起，我可能想提取相应列和行中的值，并将该值作为标签放入tkinter中，但是由于表中包含数字之间的逗号，因此出现了上述错误，因此我应该怎么转换它们才能得到值？因为我不知道如何处理对应值中的逗号

我无法从网络表获取数据值
