THANKS!!!
(PLESE DON'T SAYS ME:agly?)

P.S.:(important)
running on pycharm ,the code is fine.
but on the cloud server is wrong.

For all practical purposes you cannot have Tkinter GUI running on Colab.
You can emulate display but you will not be able to interact with it.

On a general note - Please, don't ask/offer people to edit your code directly online. You should post enough information (minimal reproducible example) - code (in python tags), traceback (in error tags), input/output data, etc. so that people on the forum can reproduce the problem and answer.
I strongly advise you to visit the help center
