Mac OS Monterey Python Version?

For anyone who has Mac OS Monterey installed, it's just a case of opening up Terminal and running 'python --version'.

There is a tool I use that may stop working if the system Python version changes.

Python 2 is version 2.1.18 and Python 3 is version 3.8.9

A new macOS Monterey install shows

user@mbp16 ~ % python --version
Python 2.7.18

user@mbp16 ~ % python3 --version
xcode-select: note: no developer tools were found at '/Applications/Xcode.app', requesting install. Choose an option in the dialog to download the command line developer tools.

After a fresh install you'll have the following:

$ python --version && which python
Python 2.7.18
/usr/bin/python

$ python3 --version && which python3
Python 3.8.9
/usr/bin/python3

An update on realpython.com/intro-to-pyenv/  I had issues with pyenchant not being able to find enchant C library when I used pyenv installer as suggested in this link. However, when I used brew install for all packages including pyenv, pyenv-virtualenv - I was able to have multiple python virtual environments on 2.7.18, 3.9.9 on latest Monterey using M1 silicon 14" pro.

For default Python 3.8.9, I am seeing build errors for pyenv install 3.8.9 command:

pyenv install 3.8.9

python-build: use openssl@1.1 from homebrew

python-build: use readline from homebrew

In another forum I learnt that 3.9.1 is the python supported for Monterey. Not the ones prior to it.

Version 3.10.0 is the latest and compatible version for macOS Monterey (macOS 10.9 or later)

[NEW] This updated installer provides a hotfix for a problem with the built-in Tk library when running on macOS 12 Monterey. See the ReadMe file for more information.

I typed that (I have 12.5.1) & I get this: zsh: command not found: python

Came across this post/thread with a problem I'm having. I'm simply trying to run a .py script on macos Monterey 12.5.1, that I found online, to see why my current/active window I'm working in loses focus. When I go to run the script, it returns an error 'ImportError: cannot import name 'NSWorkspace' from 'AppKit'. Anyone know why appkit won't import in python3, and what I need to do to rectify this error? Thanks!
