To get the most out of this book

This book assumes very little previous knowledge—only a familiarity with the fundamentals of programming. Knowledge of the Python programming language is helpful for understanding the examples, but for readers only familiar with other programming languages, the code comments and descriptions should not be too difficult to understand.

The examples in this book can be run in any Python environment with access to the required libraries, but Jupyter Lab is recommended and offers several benefits. Jupyter Lab is an interactive programming environment for Python and other languages. Jupyter Lab runs in a web browser and makes it possible to visualize outputs along with the code, as well as to easily modify and re-run chunks of code.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

G_karate = nx.karate_club_graph()
mr_hi = 0
john_a = 33

When code produces text output, that text output is set in bold:

list(nx.all_shortest_paths(G_karate, mr_hi, john_a))
[[0, 8, 33], [0, 13, 33], [0, 19, 33], [0, 31, 33]]

Bold: Indicates a new term or an important word. For example: "Statements that refer to themselves are called self-referential."
