I agree, but it can be simplified. Python 3 nowadays comes with all the needed tools built-in, so there is no need to install virtualenv:

  cd your/project/location
  python3 -m venv env
  source env/bin/activate
  pip install anything_you_like

Also, on Windows, use the Python launcher[1] (that comes with the standard install of Python for Windows) to avoid having to mess with PATH settings as you would have had to historically. Instead of calling "python" or "python3" and hoping for the right version, just call "py" and tell it which version you want:

  py -3.6-32 -m venv env

That gets you a venv with 32-bit Python 3.6, for example. Use "py -0" to list available versions.
