Instead, it’s an illustrated, fun, and hands-on guide that treats learning Python like the adventure it should be. It’s designed especially for beginners who want to understand how code works without getting overwhelmed. You’ll be guided by a cheeky, know-it-all cat who’s surprisingly good at teaching Python from scratch. Don’t worry about going through it alone; a slightly moody dachshund dog is your study buddy, learning right alongside you. Each chapter introduces a core programming concept, explains it with a playful twist, and reinforces it through human-friendly examples, analogies, and exercises. Whether you’re a software professional or someone who’s never written a single line of code, this book will help you build real Python coding skills… and even enjoy the process (shocking, right?). Forget dry tutorials and walls of text. Python Illustrated speaks to visual learners, creative thinkers, cat lovers, dog lovers, and anyone who prefers their learning with a dash of humor. From writing your first function to understanding object-oriented programming, you’ll build a solid foundation in Python (without the usual headaches). What you will learn Set up Python and write your first program Understand variables, data types, and conditional statements Use loops, lists, dictionaries, and tuples to handle data efficiently Write and use functions to create reusable code Manage files and understand object-oriented programming and inheritance Debug your Python code to ensure it works flawlessly Discover how you can keep learning and building beyond this book Who this book is forThis book is ideal for anyone with a sense of humour who’s new to Python or programming in general. It takes a step-by-step hands-on approach that will work for anyone with a practical mindset. Whether you're a student or a professional developer looking to expand your skill set, this book offers a comprehensive and enjoyable learning experience.

Refine your Java skills by seamlessly blending foundational core concepts with hands-on coding applications Key Features Gain a deep understanding of essential topics that will help you progress with Java Learn by working on mini-projects to help reinforce the concepts you’ve learned Gain comprehensive knowledge of the core concepts of Java Purchase of the print or Kindle book includes a free PDF eBook Book DescriptionLearn Java with Projects bridges the gap between introductory Java guides and verbose, theoretical references. This book is crafted to build a strong foundation in Java programming, starting from the Java environment itself. It goes far beyond a superficial review of the topics; it demonstrates, with practical examples, why these fundamentals are crucial for developing a deep understanding of the language. You'll not only learn about classes and objects but also see how these concepts are used in practical scenarios, enhancing your ability to write clean, efficient code. The engaging projects throughout the book provide real-world applications of complex topics, ensuring you can connect theoretical knowledge with practical skills. What makes this book stand out is the expertise of its authors. Seán, a seasoned university lecturer with over 20 years of experience, brings academic rigor and real-world insights, thanks to his work with a prestigious software company. Maaike, a passionate software developer and award-winning trainer, brings hands-on experience and a love for teaching. By the end of this book, you'll not only understand Java's core concepts and the critical advanced ones, but also gain practical experience through projects that mimic real-life challenges. What you will learn Get to grips with Java fundamentals to build a strong programming foundation Gain a deep understanding of the critical object-oriented principles: encapsulation, inheritance and polymorphism Apply real-world scenarios using classes, objects, and interfaces Master exception handling for robust error management Explore generics and collections to manage complex data structures Utilize lambda expressions and streams for efficient data processing Complete practical projects to reinforce theoretical knowledge Who this book is forThis book is for anyone looking to learn the core concepts of Java. If you’re learning programming (and Java) for the first time or want to upskill to Java (with experience in a different language), then this book is for you. Prior knowledge of programming is helpful but not necessary.

Improve application performance by tuning, monitoring and profiling both the garbage collector and JVMKey FeaturesUnderstand the different parts of Java memory and the various garbage collectors so you can select your preferred oneExplore how memory management can help to effectively improve performanceLearn how to spot and avoid memory leaks to enhance application performanceBook DescriptionUnderstanding how Java organizes memory is important for every Java professional, but this particular topic is a common knowledge gap for many software professionals. Having in-depth knowledge of memory functioning and management is incredibly useful in writing and analyzing code, as well as debugging memory problems. In fact, it can be just the knowledge you need to level up your skills and career.In this book, you'll start by working through the basics of Java memory. After that, you'll dive into the different segments individually. You'll explore the stack, the heap, and the Metaspace. Next, you'll be ready to delve into JVM standard garbage collectors. The book will also show you how to tune, monitor and profile JVM memory management. Later chapters will guide you on how to avoid and spot memory leaks.By the end of this book, you'll have understood how Java manages memory and how to customize it for the benefit of your applications.What you will learnUnderstand the schematics of debugging and how to design the application to perform wellDiscover how garbage collectors workDistinguish between various garbage collector implementationsIdentify the metrics required for analyzing application performanceConfigure and monitor JVM memory managementIdentify and solve memory leaksWho This Book Is ForThis book is for all levels of Java professionals, regardless of whether you're a junior or senior developer, a DevOps engineer, a tester, or the system admin of a Java application. If you currently don't have in-depth knowledge of Java memory, garbage collection, and/or JVM tuning, then this book will help you to take your Java skills to the next level.

Start your journey towards becoming a JavaScript developer with the help of more than 100 fun exercises and projectsKey Features: - Write eloquent JavaScript and employ fundamental and advanced features to create your own web apps- Interact with the browser with HTML and JavaScript, and add dynamic images, shapes, and text with HTML5 Canvas- Build a password checker, paint web app, hangman game, and many more fun projectsBook Description: This book demonstrates the capabilities of JavaScript for web application development by combining theoretical learning with code exercises and fun projects that you can challenge yourself with. The guiding principle of the book is to show how straightforward JavaScript techniques can be used to make web apps ranging from dynamic websites to simple browser-based games.JavaScript from Beginner to Professional focuses on key programming concepts and DOM (Document Object Model) manipulations that are used to solve common problems in professional web applications. These include data validation, manipulating the appearance of web pages, working with asynchronous and concurrent code, and much more.The book follows project-based learning to provide context for the theoretical components in a series of code examples that can be used as modules of an application, such as input validators, games, and simple animations. This will be supplemented with a brief crash course on HTML and CSS to illustrate how JavaScript components fit into a complete web application.As you learn the concepts, you can try them in your own editor or browser console to get a solid understanding of how they work and what they do.
