 From the LibreOffice 4.0beta1 release notes

Python

The bundled Python was upgraded from Python 2.6 to Python 3.3 (Michael

Python extensions and macros may require some degree of re-work to work 
on the latest Python; see for example Porting to Python 3.

The last is a link to Lennart Regebro's book: http://python3porting.com/
