title: How to use the latest version of python in emacs?
body: <p>I have installed python 2.7.8 in Cygwin and python 2.7.9 on my drive (<code>C:/Python27/python.exe</code>). </p>
  
  <p>My question is: whenever I do <code>M-x python2.7</code> in emacs, I always end up using the python 2.7.8 in Cygwin and this is not what I want. I want to be able to use the latest python 2.7.9 on my drive. </p>
  
  <p>I tried the following but it did not give me what I want: </p>
  
  <pre class="lang-lisp prettyprint-override"><code>(add-to-list 'load-path "C:/Users/mynameis/.emacs.d/python-mode.el-6.1.3")
  (setq py-install-directory "C:/Users/mynameis/.emacs.d/python-mode.el-6.1.3")
  (require 'python-mode)
  </code></pre>
  
  <p>How can I use Python2.7.9 in emacs ? </p>
