[Tutor] python -m pip install vs pip install

[Alex Kleider]

In another currently active thread Mats Wichmann recommends using:
   python -m pip install ...
vs
   pip install ...

The question is how to install a specific version of python itself.

I'm running Ubuntu 16.04 and have the following notes to myself as to 
how to install version 3.6 which was the one I wanted at the time:

   sudo add-apt-repository ppa:jonathonf/python-3.6
   sudo apt-get update
   sudo apt-get install python3.6
   pip install --user virtualenvwrapper
   echo "source virtualenvwrapper.sh" >> ~/.bashrc
   source ~/.bashrc
   mkvirtualenv --python=python3.6 p36

Should I modify these notes?
What should I do if/when I'm looking to use the next version (3.7 and 
beyond?)
Will things be completely different if/when I finally decide to move up 
to Ubuntu 18.04?

Thanks,
Alex
