I recommend avoiding the version of python that comes preinstalled on macOS for the following reasons:
- It is not the latest version
- Older releases of macOS do not have python3
- Adding packages / libraries may break system functionality
- Separation of development vs. system
One of the easiest ways to install and manage the latest version of python3, and other software, is to use the Homebrew package manager.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
brew install python3
Validate python3 is working:
