About the Book
Learn how to program with Python 3 from beginning to end. Python 101 starts off with the fundamentals of Python and then builds onto what you've learned from there. The audience of this book is primarily people who have programmed in the past but want to learn Python. This book covers a fair amount of intermediate level material in addition to the beginner material.
To cover all this information, the book is split into five parts.
Part One
The first part is the beginner section. In it you will learn all the basics of Python. From Python types (strings, lists, dictionaries) to conditional statements to loops. You will also learn about comprehensions, functions and classes and everything in between!
Part Two
This section will be a curated tour of the Python Standard Library. The intent isn't to cover everything in it, but instead it is to show the reader that you can do a lot with Python right out of the box. We'll be covering the modules I find the most useful in day-to-day programming tasks, such as os, sys, logging, threads, and more.
Part Three
An all intermediate section covering lambda, decorators, properties, debugging, testing and profiling.
Part Four
Now things get really interesting! In part four, we will be learning how to install 3rd party libraries (i.e. packages) from the Python Package Index and other locations. We will cover easy_install and pip. This section will also be a series of tutorials where you will learn how to use the packages you download. For example, you will learn how to download a file, parse XML, use an Object Relational Mapper to work with a database, etc.
Part Five
The last section of the book will cover how to share your code with your friends and the world! You will learn how to package it up and share it on the Python Package Index (i.e. how to create an egg or wheel). You will also learn how to create executables using py2exe, bb_freeze, cx_freeze and PyInstaller. Finally you will learn how to create an installer using Inno Setup.

Nick Russo
Network Consulting Engineer (CCDE/CCIEx2)
Python programming is quickly becoming a critical skill for network engineers and architects. As a former-coder-turned-networker, I found this book to be refreshingly easy to read with succinct examples. I follow along step-by-step with Mike to code his examples and see the outputs for myself, which builds confidence. This is among the best resources for network engineers who need to brush up on their Python skills or learn Python for the first time. I highly recommend this book!
