Python is the perfect “first programming language.” It’s easy for beginners to read and understand, and since it’s so widely used, you can apply what you’ve learned practically anywhere. Now, there’s a simple, up-to-date beginner’s tutorial that will help you master the newest versions of Python: Sams Teach Yourself Python in 24 Hours, Second Edition.
Completely rewritten by pioneering Python developer and advocate Katie Cunningham, this guide teaches simply and clearly, through 24 concise, hands-on lessons focused on knowledge you can apply immediately. Each lesson builds on what’s come before, showing exactly how to get practical results fast.
Cunningham doesn’t stop with syntax: she guides you towards building large real-world projects, including dynamic websites, games, and stand-alone applications. Using a running case study, every chapter makes real world connections between technical skills and their practical applications.
Throughout, step-by-step instructions walk you through key tasks... Q and As, Quizzes, and Exercises test your knowledge... “Did You Know?” tips offer insider advice... “Watch Out!” alerts help you avoid problems. By the time you’re finished, you won’t just understand core Python concepts: you’ll be comfortable writing useful Python software.
