Hello!
We will have Python3 in Mageia 2, but we don't build modules in the Py3
version.
http://pkgs.org/search/?keyword=python3 is showing a long list of
modules for Fedora and very short list for Mageia.
Preparing Py3 versions is quite simple - here is an example
http://svnweb.mageia.org/packages/cauldron/python-pyparsing/current/SPECS/python-pyparsing.spec?view=markup
We have just to prepare two concurrently build roots, one for each
python version.
Fedora has a list of Py3 compatible modules

Regards!
