title: Checking version after installing Python 3.4.4 on Windows vista gives unexpected results
body: <p>I just installed Python 3.4.4 recently by running the installer and changing the environment variables. I also tried some simple commands to see if it was installed correctly and it was. However, when I typed <code>python -v</code> into the command line, this is what I got:</p>

  </code></pre>
  
  <p>Alternately, when I typed <code>python -version</code>, this is what I got:</p>
  
  <pre><code>Unknown option: -e
  usage: python [option] ... [-c cmd | -m mod | file | -] [arg] ...
  Try `python -h' for more information.
  </code></pre>
  
  <p>So I am not sure if there was any part that I installed wrongly that led to these. Hope someone can help.</p>
