I'm working in a shared machine with no root privileges, but Python 2.y installed, but I would like to have both flavors of Python, also I would like to call Python 2.y just typing python (as usual) and for calling Python 3.x, type python3. I understand that this is possible because in my main equipment (whit root access, and the magic of sudo) I can "select" which one to use.

You can install pyenv with the pyenv installer script and then run pyenv install 2.7.14 and pyenv install 3.6.3.
Some more documentation is here
Use virtualenv to handle your python dependencies. This way you can manually "select" which python version to use with your project.
