no.  You cannot really install multiple python version..

I usually install tox in a virtualenv itself.  If i then run tox, it
will create its own separate virtualenv environments and it uses the
tox.ini-specified python interpreters for creating them.  tox will
then install pytest in those separate virtualenvs and then execute
the commands specified in tox.ini.  From your output it seems that
this successfully worked for python2.7 but not for python3.3 and i
suspected this is because "python3.3" is not in your PATH environment
varaible and therefore tox cannot find it.

hope this clarifies and sorry for failing to explain this more properly,
