Answer 1

Your problem is here:

Btn_Done = Button( root , text = "Convert" , command = Donn() )

The parameter to command needs to be a function, but you are not passing a function. You are CALLING the function and passing what it returns, which is None . To fix it, pass the function itself:

Btn_Done = Button( root , text = "Convert" , command = Donn )
