I can't tell if by "set it up" to have Python binaries available for
only one user, or if you want one user to use a different Python version
from other users, with multiple Python versions potentially available to
all users, which would be then "Gentoo way".

If you have, for example, Python 2.7 and 3.6 installed, you can use
"eselect python set ..." to configure the default Python for most users.
For individual users, I recommend a Python virtual environment. You can
use the 'virtualenv' module for both Python 2.7 and 3.x, but since Python
3.5 the built-in 'venv' module is recommended.

I know soft links to a specific Python version were recommended here,
but based on my experience I strongly discourage that. Your special user
will need more than just the binaries, and a venv is definitely the more
robust and versatile way to go.
