You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.
The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.
Information on tools for unpacking archive files provided on python.org is available. Tip: even if you download a ready-made binary for your platform, it makes sense to also download the source. This lets you browse the standard library (the subdirectory Lib ) and the standard collections of demos ( Demo ) and tools ( Tools ) that come with it.
Doing it Right¶
Let’s install a real version of Python.
Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.
Note
If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.
Note
Pop-ups aren't always annoying. Sometimes you need them for features or secure logins. We show you how to allow pop-ups on a Mac in Chrome, Firefox, and Safari. $ python -version Python 2.7.15. Above instructions for “install python 3 on mac using homebrew” worked perfectly on a new macbook air Feb 2020. By default, your Mac comes installed with Python 2.7, no installation necessary! However, if you want some of the new features of Python such as 'print' being a function now instead of a standalone command, then you are going to want to install Py.
If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running
xcode-select--install
on the terminal.While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.

Now, we can install Python 3:

Pipenv & Virtual Environments¶
The next step is to install Pipenv, so you can install dependencies and manage virtual environments.
A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.
