Python Crash Course, 3rd Edition
Python Crash Course is the world’s best-selling guide to the Python programming language. This fast-paced, thorough introduction will have you writing programs, solving problems, and developing functioning applications in no time.
You’ll start by learning basic programming concepts, such as variables, lists, classes, and loops, and practice writing clean code with exercises for each topic. You’ll also learn how to make your programs interactive and test your code safely before adding it to a project. You’ll put your new knowledge into practice by creating a Space Invaders–inspired arcade game, building a set of data visualizations with Python’s handy libraries, and deploying a simple application online.
As you work through the book, you’ll learn how to:
• Use powerful Python libraries and tools, including pytest, Pygame, Matplotlib, Plotly, and Django
• Make increasingly complex 2D games that respond to keypresses and mouse clicks
• Generate interactive data visualizations using a variety of datasets
• Build apps that allow users to create accounts and manage their own data, and deploy your apps online
• Troubleshoot coding errors and solve common programming problems
New to this edition: This third edition is completely revised to reflect the latest in Python code. New and updated coverage includes VS Code for text editing, the pathlib module for file handling, pytest for testing your code, as well as the latest features of Matplotlib, Plotly, and Django.
If you’ve been thinking about digging into programming, Python Crash Course will provide you with the skills to write real programs fast. Why wait any longer? Start your engines and code!

Preface to the Third Edition
"I am not at all surprised that the Python Crash Course book has sold 1.5 million copies and counting. This 3rd edition, with its numerous updates and additions, is likely to double this number. You could start out knowing nothing about Python and end up an expert programmer by the time you reach the end of the book. It makes no assumptions, moves the reader from the basics through to working through a series of challenging programs. Everything you need to know is included. And did I mention that it's a LOT of fun? Learning python is a smart investment of your time because the language is efficient and powerful. This book will get you where you need to be to program like a pro."
—Sandra Henry-Stocker, NetworkWorld
"Eric Matthes's Python Crash Course, 3rd Edition takes a well-regarded text for getting started with Python and brings it up to date for 2023. The book not only covers Python's basics but lets you put them to use in a series of projects involving data analysis, web development, and gaming. Many books offer either Python basics or projects to learn from. This one delivers both."
—Serdar Yegulalp, InfoWorld
Reviews for the 2nd Edition:
Python Crash Course selected as one of the best books for learning Python by Real Python
"With a patient and experienced pedagogical style, and a combination of thorough language instruction and plenty of illustrative sample code, Python Crash Course is a terrific way to begin learning computer programming in general and the Python language in particular."
—Michael J. Ross, web developer and former Slashdot contributor.
“It has been interesting to see, over the last few years, No Starch Press, which produces this book, growing and producing future classics that should be alongside the more traditional O’Reilly Press programming books. Python Crash Course is one of those books.”
—Greg Laden, ScienceBlogs
“All of these projects are well thought out and presented in such a way that learning the subject matter and implementing it is much more an enjoyable pastime rather than an onerous task that must be completed. Eric took the time to deal with some rather complex projects and lay them out in a consistent, logical and pleasant manner that draws the reader into the subject willingly, which unfortunately, many authors fail to do.”
—Full Circle Magazine
“The book is well presented with good explanations of the code snippets. It works with you, one small step at a time, building more complex code, explaining what's going on all the way.”
“Learning Python with Python Crash Course was an extremely positive experience! A great choice if you’re new to Python.”
—Mikke Goes Coding
"While Python Crash Course uses Python to teach you to code, it also teaches clean programming skills that apply to most other languages."
—Great Lakes Geek
"It does what it says on the tin, and it does it really well. If you want a crash course in Python, fear not!!! The Python Crash Course is an excellent book that provides a thorough introduction to Python that will have you writing programs and solving problems in no time!"
—Technical YA, Best Books to Learn Python Language in 2021
—Anna Yukhtenko, Senior Games Analyst at Hutch
"I recommend this book to anyone learning python. It is my best resource so far."
—Firdaus H. Salim, @BetaScribbles
"The fastest way to learn Python."
—Learning Python, Youtuber
"Eric Matthes's passion for teaching really shines through . . . Clearly introduces every new concept."
—makes sense, YouTuber
