Python3 now included with Ventura

Correction to my OP: python3 is not included in Ventura, but it can be added by installing the command-line tools with:

xcode-select --install

(https://osxdaily.com/2014/02/12/install-command-line-tools-mac-os-x/), and after installation, it has the benefit of being updated with macOS updates

Seems I had an old version of the commas line tools on my mac-mini (intel) that wasn't being updated with Software Update. I deleted  /Library/Developer/CommandLineTools and reinstalled (xcode-select --install) and now python 3.9.6 is installed

Still at least a year behind the current Python 3.10.8 distribution. Sad.

A year behind isn’t that bad, and understandable (raspberrypiOS also has 3.9.2) and as an infrequent python user, I prefer the distribution included with the command line tools.

Not a fan as how python.org handles macOS updates by not removing the prior versions and I’m left with multiple versions in my App Folder, and in Frameworks.

Yes, ask me how I know about multiple versions of Python.org and the script that I had been using to clean that up…

Did you catch all the changes to $PATH that python made to .bash_profile?

I use Zsh and not Bash, though no changes were made to any Bash dotfile. I do see that in my .zshrc, the old reference to Python 3.10 remains, so I will have to change that.

bash, zsh, sh, whatever shell is used, python has to update the Path to include: /Library/Frameworks/Python.framework/Versions/3.10/bin for 3.10, and there should be a .pysave file somewhere as well.

…and the Python 3.11.0 installation with the Python.org installer did not update any PATH statement. The old Python 2.7.* installers would enter a separate PATH statement in the dot files, but v3.* does not for me.

If it’s not 1st in the PATH, then how does python3 3.11 in Terminal 1) find it, and 2) run it instead of python3 in /bin/bash? Could be the python installer added it to  /etc/paths.d/

I have not upgraded to Ventura, but is Python 2 still in it?

Python 2.7 is not included in Ventura.

Also, I must correct my initial post as python3 is not included in Monterey, but it can be added by installing the command-line tools with: xcode-select --install (https://osxdaily.com/2014/02/12/install-command-line-tools-mac-os-x/), and after installation, it has the benefit of being updated with macOS updates

If you're updating to python3, there is a python code conversion tool include with the command line tools (/Library/Developer/CommandLineTools/usr/bin//2to3)

Usage: 2to3 [options] file|dir ...

Options:
  -h, --help            show this help message and exit
  -d, --doctests_only   Fix up doctests only
  -f FIX, --fix=FIX     Each FIX specifies a transformation; default: all
  -j PROCESSES, --processes=PROCESSES
                        Run 2to3 concurrently
  -x NOFIX, --nofix=NOFIX
                        Prevent a transformation from being run
  -l, --list-fixes      List available transformations
  -p, --print-function  Modify the grammar so that print() is a function
  -e, --exec-function   Modify the grammar so that exec() is a function
  -v, --verbose         More verbose logging
  --no-diffs            Don't show diffs of the refactoring
  -w, --write           Write back modified files
  -n, --nobackups       Don't write backups for modified files
  -o OUTPUT_DIR, --output-dir=OUTPUT_DIR
                        Put output files in this directory instead of
                        overwriting the input files.  Requires -n.
  -W, --write-unchanged-files
                        Also write files even if no changes were required
                        (useful with --output-dir); implies -w.
  --add-suffix=ADD_SUFFIX
                        Append this string to all output filenames. Requires
                        -n if non-empty.  ex: --add-suffix='3' will generate
                        .py3 files.
