As I understand this wiki page, you only need to specify a particular python 
version if you require a specific slot installed, which happens to be 
different from the default python slots managed by normal portage usage and 
reverse dependencies of individual packages.

In order to use the latest stable python versions, I would remove any manually 
specified python targets from make.conf, then 'emerge @preserved-rebuild', 
then 'emerge --depclean -v -p' and for good measure 'revdep-rebuild'.  When 
python 2.7 becomes deprecated in the future it will fall out of the portage 
tree and your regular emerge will unmerge it.
