title: How to get PyCharm IDE to do code completion for pygame's sub-modules?
body: <p>Intro: pygame is a python module used to create games. I've properly installed the module and my PyCharm successfully imports it.</p>
  
  <p>I'll jump straight to an example scenario:</p>
  
  <p>Trying to use the get code completion for the sub-module "image" under pygame works fine:</p>
  
  <pre><code>pygame.image
  </code></pre>
  
  <p>When I type further and try to get code completion under image, it doesn't work:</p>
  
  <pre><code>pygame.image.  # shows a suggestions list, but list doesn't contain any
                 # function names under the pygame.image sub-module
  </code></pre>
  
  <p>I've been trying for ages. The <em>python console within PyCharm can do this</em> (it uses IPython, correct me if I'm wrong) but the editor cannot.</p>
  
  <p>PS apologies for not showing screenshots for the above, I don't have enough stackoverflow points to post images</p>
