Portable executable on OSX
hi all, I would like to have a portable executable of python3 on OSX. I google a lot about it, but I could not find any solution. Am I missing something or is it simply not possible? thanks -- https://mail.python.org/mailman/listinfo/python-list

Am I missing something or is it simply not possible? I'm not sure what you mean. My Mac comes presupplied with Python 3, and I'd expect any modern Mac to be the same. So a python 3 programme should work on any Mac. If you mean: "how do I write a Python script to use python 3?" the usual approach is to start the script with a shebang line like this: #!/usr/bin/env python3 On _any_ UNIX or UNIXlike system (OSX/MacOS is a BSD derived UNIX) this will run the script with your usual "python3" command if you invoke the script as a command.

Re: Portable executable on OSX
"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.

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.) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
Third round of the Smart Iterator Challenge: September-October 2022
Challenge-week 3: Generalising the solution, starts today! Details from the Meetup site: https://www.meetup.com/nzpug-auckland/events/288813734/ A virtual event run by the Auckland Branch of the New Zealand Python Users' Group. It's Week 3 of the Smart Iterator Challenge! Time to see how modules and namespaces provide building-blocks which enable us to cope with change. Can you anticipate and manage change? The tutorial demonstrates SOLID's SRP (and a bit of OCP) for those who want to learn more than Python-coding. This Challenge will interest Python-Journeymen, and Python-Apprentices ready to move-on from ‘the basics’. There is a separate-but-related question for Python-Masters and any advanced Journeymen who are finding the main Challenge too-easy (available upon personal request), in recognition of being prepared to help others. We start with a review of Challenge-week 2 and a sample-answer to download and compare with your own efforts. Challenge-week 3 starts with either your own or a provided template-script, so you don't have to have completed Challenge-weeks 1 and 2 (but it will help). Again, there is a tutorial in case you haven't met namespaces before. Followed by multiple specifications to implement. In many ways, the challenge is not so much writing code, as it is designing a code-solution. Putting code-modules together, something like a jig-saw puzzle! Challenge Schedule: Generalising the solution Starting: Sat 22 Oct Office Hours: 1830*, Wed 26 Oct Concluding: midnight after Sun 30 Oct * all times NZDT (UTC+13) Are you up for a challenge?
