title: Python import enum error
body: <p>Having trouble using Enum. Running Python 2.7 on Linux Debian Distribution.<br>
  Installed enum package as well as enum34 package for older Python version compatibility.</p>
  
  <p>When I try to import enum with this command in my python module:</p>
  
  <pre><code>from enum import Enum
  </code></pre>
  
  <p>I get the error:</p>
  
  <pre><code>from enum import Enum
  ImportError: No module named enum
  </code></pre>
  
  <p>I've tried using:</p>
  
  <pre><code>import enum
  </code></pre>
  
  <p>and</p>
  
  <pre><code>import enum34
  </code></pre>
  
  <p>with no luck... Getting errors respectively:</p>
  
  <pre><code>ImportError: No module named enum
  </code></pre>
  
  <p>and</p>
  
  <pre><code>ImportError: No module named enum34
  </code></pre>
  
  <p>The way I'm trying to use Enum is:</p>
  
  <pre><code>class Callable_Options(Enum):
       function_callable   = 0
       help_param_callable = 1
       help_str_callable   = 2
  </code></pre>
  
  <p>But my module errors before this.</p>
  
  <p>Any idea how to get Enum working?</p>
  
  <p>Thanks.</p>
  
  <p>EDIT:</p>
  
  <p>Note that I had to change my class to inherit the object </p>
  
  <pre><code>class Callable_Options(IntEnum):
  </code></pre>
  
  <p>instead of </p>
  
  <pre><code>class Callable_Options(Enum):
  </code></pre>
  
  <p>To be able to use the attributes to index a list</p>
