"Portable executable" usually means that the program resides on
removable media, like a USB stick. You can go to a computer, plug the
stick in, and run the program. If it's Python, then the installation on
the removable medium needs to set up all the paths and directories
correctly before actually running Python. That would typically be done
with batch files setting paths and environmental variables.

I got this working for Python on Windows some years ago. Here is the
setup batch file I used - it gets executed when the user types "pyth37":

@echo off
setlocal
: Find effective drive for this file.
set ed=%~d0
path %ed%\python37\Scripts;%ed%\python37;%PATH%
set PYTHONUSERBASE=%ed%\user\python
set HOME=%ed%\user\python
call python %*
endlocal

It might need to be be more complex on MacOS, but it gives you the idea.
The odd-looking line "set ed=%~d0" is a Windows-specific way to get
the drive of the command file being run.

Basic idea looks sound. Might actually be _easier_ on OSX, since it's
Unix-like and you should be able to depend on /bin/bash. The notation
`dirname $0` should give you the path to the current script, from
which everything else can be calculated.

(Caveat: Never actually done this on a Mac, and only did cursory web
searching to check that it wasn't a ridiculous idea.)
