title: How to set Python IDLE to use certain python version
body: <p>I am using Windows 8.</p>
  
  <p>Python version 2.7.3 have been installed on my computer together with another software. </p>
  
  <p>Now I have installed python 3.3.5 and i want to use this version from now.
  But everytime I run Python IDLE it runs version 2.7.3.
  Even if I go to C:\Python33\Lib\idlelib\idle.pyw and run idle.pyw it runs with the 2.7.3 version.</p>
  
  <p>I thought that every python version install its own IDLE so I am quiet confused here.</p>
  
  <p>When I run Hello world program from the console it runs using the version 3.3.5 I have checked that.</p>
  
  <p>So what I need to do is to run IDLE using 3.3.5 version</p>
  
  <p>Anybody knows what to do?</p>
