ABSTRACT
In this chapter you learn about IPython , an interface that allows you to use Python interactively with tools that have been optimized for mathematical and computational tasks. You learn how to use IPython as a calculator and how to add, subtract, multiply, divide, and perform other common mathematical functions. You also learn the basic elements of the Python programming language, including functions , variables , and scripts , which are rudimentary computer programs. We introduce Python modules , which extend the capabilities of the core Python language and allow you to perform advanced mathematical tasks. You also learn some new ways to navigate your computer’s file directories. Finally, you learn how to get help with Python commands and functions.
