title: How to customize the label of a tkinter Scale widget by adding a percentage sign
body: <p>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?</p>
  
  <p>I want it to look like the following (roughly):</p>
  
  <pre><code>             75%  
  |-------------o----|
  </code></pre>
  
  <p>Currently I cannot figure a way to add that percent sign. Any help, or a definitive "that is not possible" would be appreciated. Thanks.</p>
