title: Python return for another function
body: <p>im working with PyOpenGL, and i want to make small RGB converter function.
  PyOpenGL for color use floating numbers from 0 to 1.
  So 0 0 0 - Black
  1 1 1 - White.
  Im make this:</p>
  
  <pre><code>def RGB(Red, Green, Blue):
      Red = 1 / 255 * Red
      Green = 1 / 255 * Green
      Blue = 1 / 255 * Blue
      return Red, Green, Blue
  </code></pre>
  
  <p>And im using him like this: </p>
  
  <pre><code>glClearColor(RGB(255, 255, 255), 1)
  </code></pre>
  
  <p>But i get error: </p>
  
  <pre><code>this function takes 4 arguments (2 given)
  </code></pre>
  
  <p>I can't understand how to return multiple arguments</p>
