On Mac the recommended approach is to use the official Python.org installer. Previously the package manager Homebrew was a great choice–it handled software installs and upgrades elegantly in most cases–but for Python itself there are several serious issues detailed by Justin Mayer in this post.

How to install Python 3 on a Mac computer. On Mac the recommended approach is to use the official Python.org installer. Previously the package manager Homebrew was a great choice–it handled software installs and upgrades elegantly in most cases–but for Python itself there are several serious issues detailed by Justin Mayer in this post. For most Unix systems, you must download and compile the source code. The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms. Download the latest Python 3 and Python 2 source. I want to install pip for python 2.7 on my Mac. I think this is the python located in /usr/bin/python. Unfortunately I have already installed Anaconda, which installs python 3.6.3, and changes things so that the command python xxx.py automatically runs xxx.py using python 3.6.3.
Main development now takes place in the Python standard library: see the Python developer’s guide, and report issues on the Python bug tracker. However, if you find an issue specific to prior versions of Python (such as 2.7 or 3.2), you can post an issue on the BitBucket project page. Installing Packages¶. This section covers the basics of how to install Python packages. It’s important to note that the term “package” in this context is being used to describe a bundle of software to be installed (i.e. As a synonym for a distribution).

IDLE vs Command Line
The simplest way to use Python is via the built-in IDLE. Click on the link for IDLE which launches a new Shell. You can type any command here such as print('Hello, World').
You can also now access Python from the command line. Open up the Terminal application which is located within Applications -> Utilities -> Terminal.
Once open, type python3 to launch the Python interpreter from the command line. When you see the prompt >>> you know it is working. To confirm, type print('Hello, World') again.
