title: Convert a string to a tuple
body: <p>I read some tuple data from a file.  The tuples are in string form, for example <code>Color["RED"] = '(255,0,0)'</code>.  How can I convert these strings into actual tuples?</p>
  
  <p>I want to use this data in PyGame like this:</p>
  
  <pre><code>gameDisplay.fill(Color["RED"])
  # but it doesn't have the right data right now:
  gameDisplay.fill('(255,0,0)')
  </code></pre>
