title: Cannot import python http module for twisted.web
body: <p>I am trying to execute a python program that uses twisted web, but for some reason it cannot import http.  I am new to this and I am not really familiar enough to solve this issue.  I have done some googling and I can't really find anything that seems relevant to this particular issue, only some vaguely similar things that don't seem to resolve the issue.</p>
  
  <pre><code>Traceback (most recent call last):
    File "./test.py", line 27, in &lt;module&gt;
      from twisted.web import http
  ImportError: cannot import name http
  </code></pre>
  
  <p>OS: CentOS 5.9
  Python version: 2.7.5</p>
  
  <pre><code>$ yum list installed | grep twisted
  python-twisted-core.i386              2.5.0-4.el5                      installed
  python-twisted-web.i386               0.7.0-1.el5                      installed
  </code></pre>
  
  <p>Here is what the import looks like:</p>
  
  <pre><code> from twisted.web import http
  </code></pre>
