It will probably be easier to delete the python3 files,
when you have the new Python 3.3.x present in /opt/.
Then you can identify exactly which files to delete in /usr/local/.
Installing Python-3.3.x :
( There is no Python-3.3.3 AFAIK. 3.3.2 is the stable version )
$ tar xvf Python-3.3.2.tar.xz
$ cd Python-3.3.2/
$ ./configure --prefix=/opt/python3
$ make ( A few minutes to finish, on my Intel i7 920.)
$ su <Enter-root-password>
# make install
Using : $ /opt/python3/bin/python3.3 <etc. etc.>
