A comprehensive guide to exploring modern Python through data structures, design patterns, and effective object-oriented techniques Key Features Build an intuitive understanding of object-oriented design, from introductory to mature programs Learn the ins and outs of Python syntax, libraries, and best practices Examine a machine-learning case study at the end of each chapter Book Description Object-oriented programming (OOP) is a popular design paradigm in which data and behaviors are encapsulated in such a way that they can be manipulated together. Python Object-Oriented Programming, Fourth Edition dives deep into the various aspects of OOP, Python as an OOP language, common and advanced design patterns, and hands-on data manipulation and testing of more complex OOP systems. These concepts are consolidated by open-ended exercises, as well as a real-world case study at the end of every chapter, newly written for this edition. All example code is now compatible with Python 3.9+ syntax and has been updated with type hints for ease of learning. Steven and Dusty provide a comprehensive, illustrative tour of important OOP concepts, such as inheritance, composition, and polymorphism, and explain how they work together with Python's classes and data structures to facilitate good design. In addition, the book also features an in-depth look at Python's exception handling and how functional programming intersects with OOP. Two very powerful automated testing systems, unittest and pytest, are introduced. The final chapter provides a detailed discussion of Python's concurrent programming ecosystem. By the end of the book, you will have a thorough understanding of how to think about and apply object-oriented principles using Python syntax and be able to confidently create robust and reliable programs. What you will learn Implement objects in Python by creating classes and defining methods Extend class functionality using inheritance Use exceptions to handle unusual situations cleanly Understand when to use object-oriented features, and more importantly, when not to use them Discover several widely used design patterns and how they are implemented in Python Uncover the simplicity of unit and integration testing and understand why they are so important Learn to statically type check your dynamic code Understand concurrency with asyncio and how it speeds up programs Who this book is for If you are new to object-oriented programming techniques, or if you have basic Python skills and wish to learn how and when to correctly apply OOP principles in Python, this is the book for you. Moreover, if you are an object-oriented programmer coming from other languages or seeking a leg up in the new world of Python, you will find this book a useful introduction to Python. Minimal previous experience with Python is necessary.

The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications Ruby's widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution. The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. This book focuses squarely on object-oriented Ruby application design. Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

A Concise and Practical Introduction to Programming Algorithms in Java has two main goals. The first is for novice programmers to learn progressively the basic concepts underlying most imperative programming languages using Java. The second goal is to introduce new programmers to the very basic principles of thinking the algorithmic way and turning the algorithms into programs using the programming concepts of Java. The book is divided into two parts and includes: The fundamental notions of variables, expressions and assignments with type checking - Conditional and loop statements - Explanation of the concepts of functions with pass-by-value arguments and recursion - Fundamental sequential and bisection search techniques - Basic iterative and recursive sorting algorithms. Each chapter of the book concludes with a set of exercises to enable students to practice concepts covered.

You will first be introduced to object-oriented programming, then to the basics of objects in JavaScript. This book takes a do-it-yourself approach when it comes to writing code, because the best way to really learn a programming language is by writing code. You are encouraged to type code into Firebug's console, see how it works and then tweak it and play around with it. There are practice questions at the end of each chapter to help you review what you have learned. For new to intermediate JavaScript developer who wants to prepare themselves for web development problems solved by smart JavaSc.

This book aims to present the concepts and techniques of object-oriented programming as simply as possible so that it can be easily understood and mastered by beginners. The emphasis is on presenting concepts at the right time and with the right amount of detail to encourage learning and mastery of the material. The book does not focus on the Java programming language; rather, Java is used as a vehicle to implement the object-oriented concepts presented in the book.To help readers become familiar with the Java programming language, the book starts off by describing the basic features of the language. These include data types and variables, arrays, control structures (if, while, for, etc.), and performing input and output. Several exercises have been carefully designed so that readers can get up to speed with Java as quickly as possible.The book strikes a good balance between theory and practice. Some object-oriented concepts often require lengthy explanations for beginners to fully understand the concepts. Based on years of experience in teaching object-oriented programming, the book condenses long explanations in favour of providing real examples which show how the concepts are implemented in an object-oriented program. Thus, detailed code examples are liberally interspersed with theoretical descriptions throughout the book. One of the unique features of the book is that it contains five chapters (called “Programming Projects”) which explain how to build a complete object-oriented program based on the material presented in the other chapters. These chapters appear when all the relevant material required for writing the program has been thoroughly discussed in the preceding chapters. Each of the five chapters starts by describing the problem in narrative form. The chapter then gives a detailed definition of the functionality required. Next, the chapter explains how the functionality can be implemented using the object-oriented concepts presented earlier in the book. The chapter ends with a complete working Java program that solves the problem described. Often, alternative solutions are presented so that readers will be aware that there are competing ways to implement an object-oriented program with different trade-offs. Another unique feature of the book is that that new material is not used or referenced before it has been discussed. The book is essentially incremental in nature so that new concepts being introduced always build on earlier concepts. Thus, readers are only exposed to new concepts or language features when pre-requisite material has been completely discussed. Also, great care has been taken to avoid the use of programming language features which, though very useful for advanced programmers, can make it harder for a beginner to focus on and learn the object-oriented principles being imparted.This book is based on the experience gained from many years of teaching object-oriented programming to beginners who know another programming language. It is likely to benefit readers who are looking for a good, practical introduction to object-oriented programming in Java, in an easy-to-understand format.
