This application supports the core <a
href="http://www.python.org/doc/2.5/">Python 2.5</a> language, with no
module imports or file I/O.  It's meant to be used as a platform for
creating programming tutorials, not for running or debugging
production code.

<p style="margin-top: 8px;"/>Official Python 3 support is coming soon;
for now, try the <a
href="http://netserv.ict.ru.ac.za/python3_viz/">Python 3 fork</a> by
Peter Wentworth.

<p style="margin-top: 8px;"/>
Check out the <a
href="https://github.com/pgbovine/OnlinePythonTutor/">GitHub</a>
