If you want a real-world example you can look at argparse (I can
successfully pip install argparse in a Python 3.5 virtualenv even
though it's been in stdlib since 2.7).

If you want depending packages to do the work instead, they'll need
to implement environment markers with something like
;python_version<='3.3' (which really needs setuptools 17.1 or later
to interpret it correctly).
