This is not a tkinter program so its completely irrelevant to your
stated aim. In tkinter  how print works is of no importance. You will
not be using print in a tkinter program you will simply be changing
the text in a widget.

That's because you are using \r which is platform dependant
(and even terminal dependant on *nix) . You don't say which
platform you are using. Using \b (backspace) may be more

 >>> print ("test","\b\b\b\b\b\b","Foo")

But, as I say, that won't be very useful in tkinter since you
won't be using print().
