title: Python: A complete list of modules
body: <p>How do I get a list of all python modules available?</p>
  
  <p>I don't want modules of modules. Just a basic list of all modules available in <code>sys.path</code>.</p>
  
  <p><code>help('modules')</code> is not the solution, because I want it available as a variable and it imports those modules, which has side effects.</p>
  
  <p><strong>Edit</strong>: With side effects I mean libraries like kivy of <a href="http://kivy.org/" rel="nofollow">http://kivy.org/</a>, which make use of the fact, that code is executed once you import it.</p>
