How to customize the label of a tkinter Scale widget by adding a percentage sign

Question

I'm working with a Tkinter scale, where the selected value is somewhere between 0 and 100, representing a percentage. Is there a way for the value displayed to have a % percent sign following it?

I want it to look like the following (roughly):

             75%  
|-------------o----|

Currently I cannot figure a way to add that percent sign. Any help, or a definitive "that is not possible" would be appreciated. Thanks.
