Close Windows MEssage box after function call

[ashtona]

Hello, I am trying to simply display a message box on windows 10 while I am copying files/removing directories. I don't need a progress bar or anything super complicated but just simply a window that I open before I begin copying/removing and close after the functions done. Preferably would not like to use tkinter or a gui module, my program does one thing and does not require user input.

I am using shutil.copytree and shutil.rmtree

Thanks!
