title: Add “python2” path to command line on Windows 7
body: <p>I've been trying to add the <code>python2</code> path to command line on Windows 7. </p>
  
  <p>I have tried to do it this way:</p>
  
  <pre><code>C:\&gt;set python2 = C:\Python27\python.exe
  </code></pre>
  
  <p>But <code>cmd</code> told me that:</p>
  
  <pre><code>'python2' is not recognized as an internal or external command.
  </code></pre>
  
  <p>So how can I add <code>python2</code> path to command line on Windows 7?</p>
  
  <p>Thanks.</p>
