title: AttributeError: 'module' object has no attribute 'ClassType'
body: <p>Ok so I've been trying to type the command: python
  but it ends up spitting this out:</p>
  
  <pre><code>Traceback (most recent call last):
    File "C:\Python27\lib\site.py", line 62, in &lt;module&gt;
      import os
    File "C:\Python27\lib\os.py", line 398, in &lt;module&gt;
      import UserDict
    File "C:\Python27\lib\UserDict.py", line 83, in &lt;module&gt;
      import _abcoll

      Iterable.register(str)
    File "C:\Python27\lib\abc.py", line 107, in register
      if not isinstance(subclass, (type, types.ClassType)):
  AttributeError: 'module' object has no attribute 'ClassType'
  </code></pre>
  
  <p>I renamed the types.py to nottypes.py but it is still giving me the exact same message.</p>
