 The query for python3 in the last two lines in the code block above may return something similar to ``/usr/bin/python3`` and ``Python 3.8.2``, respectively (the exact version is unimportant).

+Python (python2.7.x) is no longer provided with the MacOS version 12.3 (Monterey), but is a part of standard MacOS for earlier versions. If there is no other need to install python2, you may install python3, and then create a symbolic link to set it as a default ``python``. The example below shows python3 installed using Homebrew with the path ``$BREW/bin/python3``, and subsequent link created:
 
 .. code-block:: console
 
-   /bin/bash -c "$(curl -fsSL https://github.com/alfredapp/dependency-scripts/raw/main/scripts/install-python2.sh)"

-Python3 could be installed using the similar approach:

-   /bin/bash -c "$(curl -fsSL https://github.com/alfredapp/dependency-scripts/raw/main/scripts/install-python3.sh)"

-For other Python3 installation ways and updates on MacOS refer to https://www.python.org/downloads. A 64-bit universal2 installer package is recommended (``python-3.9.11-macos11.pkg`` latest at the time of writing). Double-click on the installer package, and accept the license terms. An administrative level password will be requested for the installation. At the end of the installation, run ``Install Certificates.command`` by double-clicking on the shell script in Finder.app that opens and runs it.

+Another way to create a link is from one of User's directories, e.g., $HOME/bin, which could be added to the search $PATH for binaries:
 
 .. code-block:: console
 
-    python3 --version

-The output should now correspond to the Python version you installed.
