Описание: 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

Описание: Learn how to develop your own applications to monitor or control instrumentation hardware. Whether you need to acquire data from a device or automate its functions, this practical book shows you how to use Python's rapid development capabilities to build interfaces that include everything from software to wiring. You get step-by-step instructions, clear examples, and hands-on tips for interfacing a PC to a variety of devices.
Use the book's hardware survey to identify the interface type for your particular device, and then follow detailed examples to develop an interface with Python and C. Organized by interface type, data processing activities, and user interface implementations, this book is for anyone who works with instrumentation, robotics, data acquisition, or process control.
Understand how to define the scope of an application and determine the algorithms necessary, and why it's important
Learn how to use industry-standard interfaces such as RS-232, RS-485, and GPIB
Create low-level extension modules in C to interface Python with a variety of hardware and test instruments
Explore the console, curses, TkInter, and wxPython for graphical and text-based user interfaces
Use open source software tools and libraries to reduce costs and avoid implementing functionality from scratch |

Описание: This second edition of Foundations of Python Network Programming targets Python 2.5 through Python 2.7, the most popular production versions of the language. Python has made great strides since Apress released the first edition of this book back in the days of Python 2.3. The advances required new chapters to be written from the ground up, and others to be extensively revised.
You will learn fundamentals like IP, TCP, DNS and SSL by using working Python programs; you will also be able to familiarize yourself with infrastructure components like memcached and message queues. You can also delve into Network server designs, and compare threaded approaches with asynchronous event-based solutions.
But the biggest change is this edition's expanded treatment of the web. The HTTP protocol is covered in extensive detail, with each feature accompanied by sample Python code. You can use your HTTP protocol expertise by studying an entire chapter on screen scraping and you can then test lxml and BeautifulSoup against a real-world web site. The chapter on web application programming now covers both the WSGI standard for component interoperability, as well as modern web frameworks like Django.
Finally, all of the old favorites from the first edition are back: E-mail protocols like SMTP, POP, and IMAP get full treatment, as does XML-RPC. You can still learn how to code Python network programs using the Telnet and FTP protocols, but you are likely to appreciate the power of more modern alternatives like the paramiko SSH2 library. If you are a Python programmer who needs to learn the network, this is the book that you want by your side.
What you’ll learn
Understand low level networking
Handle sending and receiving email including composing and decoding emails, SMTP, POP and IMAP
Program the lower levels of web application programming such as FastCGI and WSGI and HTTP itself
Learn how to use memcached and message qeues using Python
Access web services using Python
Master multitasking with threads, forking, and asynchronous communication
Who this book is for
This book will be of interest to python programmers who need to program networked applications using Python. From web application developers, to systems integrators, to system administrators—this book has everything you need to know. |

Описание: As PyQt’s creator, I’m delighted to see that this book has been written. Although
I served as one of the book’s technical reviewers, I’m happy to confess
that I learned a few things myself.
The PyQt documentation covers the APIs of all the PyQt classes. This book
shows you how to use all those classes, how to combine them to create dialogs,
main windows, and entire applications—all of which look good and work well,
with no arbitrary limits, and using a programming language that is a joy
to use.
What I particularly like about the book is that the examples aren’t trivial ones
designed to illustrate a simple point, but are potentially useful in their own
right. Theway that different approaches are considered will reward the reader
who wants to develop a deeper understanding of how to apply PyQt to the
development of large scale, production quality applications. |

Описание: Это учебно-методический комплекс "Практикум по алгоритмизации и программированию на Python", который предназначен для начального знакомства с основными алгоритмами и с программированием на языке Python в интегрированных средах разработки (IDE) Geany и Eric.
Комплекс состоит из учебного пособия, в котором рассматриваются типовые задачи в рамках базового курса информатики для средней школы (с учётом требований ЕГЭ), алгоритмы их решения и реализация этих алгоритмов на языке Python и методических указаний для учителей, где
описываются особенности IDE Geany и IDE Eric, а также причины и особенности обучения программированию на Python. Кроме того, комплекс дополняется примерами программ по каждому разделу учебного пособия (32 файла с примерами вариантов разобранных задач.).
Там, где это возможно, приводится универсальное решение, которое с минимальными исправлениями может быть реализовано на других языках программирования высокого уровня и параллельно даётся решение с использованием специфики языка Python.
Дополнительно в пособии описываются основы моделирования и программирования графики в Python с использованием модуля turtle и кросс-платформенной библиотеки Tkinter.
Книга будет полезна как в учебном процессе, так и для самостоятельных занятий. |
