I've got a Python code from Google application engine. I have to implement it to Joomla.

How will you implement Python code to Joomla?

[edit following the first answer]

It's enough for me personally will be able to place the code to some module position.

Joomla is PHP based whereas Google Application Engine is Python based (and has a tendency to use Django). Your best choice would be to either find an alternative choice to the python code, hire a company to translate it, or learn python and by hand translate it.

There is no straight python to php conversion though.

EDIT: but when you want to become adventurous, you can test the Python in PHP project that is still early phase and appears to become someone's side project: http://www.csh.rit.edu/~jon/projects/pip/
