I often switch between python 3.3 and python 2.7. My virtualenv for python 3.3 is called "python33". "workon" is a virtualenv wrapper command. And check out the envlist in tox.ini on http://tox.readthedocs.org/en/latest/example/basic.html antonia@antonia-HP-2133 ~ $ workon python3.3 ERROR: Environment 'python3.3' does not exist.
