Installing Python

In this guide we are going to be using Python 3. As of creating this section, python3 is currently in version 3.6. If you are on a mac, you should already have python installed on your computer. If it is not installed you can install it from python's official installation website here.

To use python3 in terminal, you either will have to use the usually "python" command. However, if you, like me, had python2 installed first, then you will have to explicitly say "python3" so that our computers know which python version to run. Thus, whenever I use "python3" in terminal commands, I really mean to use either python3 or python, depending on which one runs python 3 for you.

To test if python is installed properly, see if you can open up the python shell by typing python in the terminal:

python

Notice how at the top when the shell is opened it says Python 3.5.1. Your python version should also be python 3.x.
