title: Problems running python in powershell terminal
body: <p>I am an absolute beginner in programming and have started learning python
  using the <em>learnpythonthehardway</em> book.
  Now, when I type python in the powershell terminal I get
  the message saying python is not recognized.</p>
  
  <p>I typed the command given by zedshaw , this one :  </p>
  
  <pre><code>[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User")
  </code></pre>
  
  <p>and I still get the same not recognized message.</p>
  
  <p>My python27 is installed in <code>D:</code> drive
  and even my windows is in <code>D:</code> drive.
  Just wanted to inform you guys,
  maybe you would need this info.</p>
  
  <p>So, what do I do now?</p>
