How is http://shell.appspot.com/ executing code online?
<p>I'm building a website which allows you to write python code online just like <a href="http://shell.appspot.com/" rel="nofollow">http://shell.appspot.com/</a> or <a href="http://ideone.com" rel="nofollow">http://ideone.com</a>. Can someone please provide me some help how I can achieve this?</p>
