It's high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development and use as a scripting or glue language to connect existing components together. Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance.

Python supports modules and packages, which encourages program modularity and code reuse. We begin as always, by running our updates. This ensures that all of our system software is up to date. Next, we will add software-properties-common. This software provides some additional scripts that are useful for adding and removing a PPA. Now, we add the repository and then run another update to allow our system to recognize the changes.

Homebrew fills this void. The script will explain what changes it will make and prompt you before the installation begins. At this point, you have the system Python 2. If the Homebrew version of Python 2 is installed then pip2 will point to Python 2. If the Homebrew version of Python 3 is installed then pip will point to Python 3.
