This list is about installing a package manager and upgrading packages
from within the package manager. See:

Once you install MacPorts, you can install any version of python
(ideally 2.7 as well as 3.5 or 3.6, ...) as well as "any other open
source software". You just run
    sudo port install python27

without any headaches with dmg files and broken paths. You might want
to remove the python you install via the above mentioned dmg.

For ipython you should install
    sudo port install py27-ipython
    sudo port install py36-ipython
