Do you want to install your packages system-wide?

Try py -3.5 -m install <the_package_I_want>

Do you want to install your python packages in a virtual environment?

Start reading here:
https://docs.python.org/3/library/venv.html

If you sometimes want a python 2.7 virtual env you cannot get it with
venv.  You will have to use the older virtualenv.
