I'm not a MacOs expert but I know MacOS uses Python in some of its tools 
so do not mess with the standard version, you might break something.

What the OS uses as Python should not necessarily impact what you use as 
Python. Usually its just a case of changing a link or creating an alias 
or environment variable.

At the worst case you can edit the shebang line of your scripts.

How are you running these scripts? Do you just double click an icon or 
do you use a commandline? If the latter what do you type?
If the former somebody with a modern Mac will need to advise.

Probably, but I don't know macports.

Have you tried calling python3 instead of just python?
That should find your Python 3.X version.
