• Learn how to do Object Oriented Programming in Python using this step-by-step tutorial
• Design public interfaces using abstraction, encapsulation, and information hiding
• Turn your designs into working software by studying the Python syntax
• Raise, handle, define, and manipulate exceptions using special error objects
• Implement Object Oriented Programming in Python using practical examples

In Detail

Object Oriented Programming is a very important aspect of modern programming languages. The basic principles of Object Oriented Programming are relatively easy to learn. Putting them together into working designs can be challenging.

This book makes programming more of a pleasure than a chore using powerful Python 3 object-oriented features of Python 3. It clearly demonstrates the core OOP principles and how to correctly implement OOP in Python.

Object Oriented Programming ranks high in importance among the many models Python supports. Yet, many programmers never bother learning the powerful features that make this language object oriented.

The book teaches when and how OOP should be correctly applied. It emphasizes not only the simple syntax of OOP in Python, but also how to combine these objects into well-designed software.

This book will introduce you to the terminology of the object-oriented paradigm, focusing on object-oriented design with step-by-step examples. It will take you from simple inheritance, one of the most useful tools in the object-oriented programmer's toolbox, all the way through to cooperative inheritance, one of the most complicated. You will be able to raise, handle, define, and manipulate exceptions.

You will be able to integrate the object-oriented and the not-so-object-oriented aspects of Python. You will also be able to create maintainable applications by studying higher level design patterns. You'll learn the complexities of string and file manipulation, and how Python distinguishes between binary and textual data. Not one, but two very powerful automated testing systems will be introduced to you. You'll understand the joy of unit testing and just how easy they are to create. You'll even study higher level libraries such as database connectors and GUI toolkits and how they apply object-oriented principles.

Harness the power of Python 3 objects; it's not just a scripting language

What you will learn from this book

• Implement objects in Python by creating classes and defining methods
• Separate different objects into a taxonomy of classes, and describe the properties and behaviors of those objects via the class interface
• Design public interfaces using abstraction, encapsulation, and information hiding
• Turn your designs into working software by learning the Python syntax
• Share implementation using inheritance
• Add functionality to the existing classes and built-ins using inheritance
• Share similar code between classes by abstracting it into a parent class
• Raise, handle, define, and manipulate exceptions using special error objects
• Understand when to use object-oriented features, and more importantly when not to
• Learn what design patterns are, and why they are different in Python
• Uncover the simplicity of unit testing and why it's so important in Python
• Utilize common Python 3 modules, libraries, and frameworks

Approach

The book begins with the very foundations of OOP and then uses practical examples to show how to correctly implement Object Oriented Programming in Python. Many examples are taken from real-world projects. The book focuses on high-level design as well as the gritty details of the Python syntax. The provided exercises inspire the reader to think about his or her own code, rather than providing solved problems.

Who this book is written for

If you're new to Object Oriented Programming techniques, or if you have basic Python skills and wish to learn in depth how and when to correctly apply Object Oriented Programming in Python, this is the book for you.

If you are an object-oriented programmer for other languages, you too will find this book a useful introduction to Python, as it uses terminology you are already familiar with.

Python 2 programmers seeking a leg up in the new world of Python 3 will also find the book beneficial, and you need not necessarily know Python 2.

Concurrency is a powerful technique for developing efficient and lightning- fast software. For instance, concurrency can be used in common applications such as online order processing to speed processing and ensure transaction reliability. However, mastering concurrency is one of the greatest challenges for both new and veteran programmers. Software developers with all levels of experience can refer to Creating Components: Object Oriented, Concurrent, and Distributed Computing in Java to better understand how concurrency works, more effectively deploy it in program components, and reuse these components to improve program design, quality, and performance.This text introduces concurrent and component programming to students, engineers, and programmers who are familiar with Java and procedural and GUI programming. It helps them to understand and apply concurrency in Java component programming, while exploring distributed program implementation, Java threads, objects, interfaces, exceptions, component reuse, and system design and management.By providing the fundamental concepts of object-oriented components and offering templates for distributed program components, this valuable resource reveals how programmers can apply concurrency and components to solve complex problems.

• The Sarbanes-Oxley Act (SOX) was passed in 2002 in response to a series of high-profile corporate scandals and requires that public companies implement internal controls over financial reporting, operations, and assets; these controls depend heavily on installing or improving information technology and business methods
• Written by one of the most visible personalities on the tech-biz side of the SOX discussion, this highly readable, engaging book provides a clear road map for integrating SOX compliance into the fabric of everyday IT infrastructure and business practice
• Shows the reader how to leverage and use service-oriented architecture (SOA), a set of technologies that enables interoperation of heterogeneous computer systems, to achieve the level of internal controls over IT that SOX mandates

Extending beyond the technical architecture to the very philosophy of how a business should operate, the Service Orientation approach establishes fluidity across boundaries to provide agility, transparency, and fundamental competitive advantage.

Service Oriented Enterprises brings the concept of service orientation from the IT department to the boardroom, applying the precepts of service oriented technology to the underlying dynamics of how a business operates. Implementing a technological concept as a cultural paradigm, the SOE succeeds by combining the best features from virtual, extended, real-time, and resilient enterprises to serve not just its customers, but also its trading partners, shareholders and employees. Building primarily on the success of the Internet and the automation of business policies and processes, the Service Oriented Enterprise (SOE) is defined by three essential layers: the enterprise performance layer, the business process management layer, and the underlying service oriented architecture. This book focuses primarily on layers two and three and how the fundamental dynamics of a business can be altered when these concepts are applied to both architecture and culture.

Beginning with an overview of the emerging SOE culture, the text contrasts the new service-oriented methodologies with traditional waterfall and iterative methodologies. Emphasizing Web Service strategies for description, discovery, and deployment techniques, the author goes deeper into service-oriented concepts describing the business process management suite as the central core of the SOE, and introducing the Enterprise Service Bus as the backbone for integration. The text describe how modeling, executing, and continuously improving the business process and business policies lends to the development of a common language between business and IT. The book concludes by expanding on these concepts and delving into the societal and behavioral aspects of the Service Oriented Enterprise.


The reality of business is no longer one where change is an unusual phenomenon; today change is the norm and the capacity for consumer-sensitive, fluid transition is vital to business survival. Service Oriented Enterprises provides the key concepts to facilitate that change.
