title: How to change Python version for Enthought Canopy?
body: <p>I installed Enthought Canopy on a Mac and it's using Apple's built-in Python 2.7.3 version. </p>
  
  <pre><code>sys.version
  Out[1]: '2.7.3 | 32-bit | (default, Jun 14 2013, 18:24:40) \n[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)]'
  </code></pre>
  
  <p>How can I change it to Python 2.7.5 which I manually installed on the computer? </p>
