Want to have a live Python console on your website, like on the python.org front page? No problem.
Use an iframe, like this:
<iframe style="width: 640; height: 480; border: none;" name="embedded_python_anywhere" src="http://www.pythonanywhere.com/embedded3/"></iframe>
Or use this link for python 2:
<iframe style="width: 640; height: 480; border: none;" name="embedded_python_anywhere2" src="http://www.pythonanywhere.com/embedded/"></iframe>
This will spawn a new "anonymous" console for each visitor to your site (unless they have a pythonanywhere account already, and are signed into it, in which case the console will actually run inside their account).
