[Tutor] I can not display the answer of the Limit when I click the Button Answer.

[edmundo pierre]

                                                           That is my code below. I used tkinter to calculate the limit of a function. I used Grid geometry, but when I click the button Answer, but nothing comes out so I do not know where I am doing wrong. I hope my code will be visible, I have tried to fixer my email. Thank you!
