Automate It!

Com um foco cada vez maior na otimização dos níveis de arquitetura e design de software, é importante que os arquitetos de software pensem em otimizações na criação de objetos, na estrutura do código e na interação entre objetos nesses níveis. Isso garante que o custo da manutenção de software seja baixo e o código seja facilmente reutilizado ou adaptável a mudanças. Aprendendo padrões de projeto em Python ajudará você a implementar cenários do mundo real com a versão mais recente de Python, a v3.5. Começaremos apresentando os padrões de projeto do ponto de vista de Python. À medida que avançar no livro, você conhecerá os padrões Singleton, Factory e Façade em detalhes. Depois disso, veremos como controlar o acesso a objetos com o padrão Proxy. O livro também inclui os padrões Observer, Command e Compound. Ao chegar ao final desta obra, você terá melhorado suas habilidades profissionais em arquitetura, design e desenvolvimento de software. Para quem este livro foi escrito Este livro foi escrito para arquitetos de software e desenvolvedores de aplicações Python apaixonados por design de software. Ele será muito útil para engenheiros com nível inicial de proficiência em Python que amam trabalhar com Python 3.5. O que você aprenderá com este livro Aperfeiçoar suas habilidades para criar uma arquitetura melhor de software. Entender soluções eficazes para problemas de design comuns. Explorar os princípios de design que formam a base do design de software, como baixo acoplamento, o princípio de Hollywood e o princípio do aberto/fechado, entre outros. Aprender como os conceitos de programação orientada a objetos são usados em aplicações de software. Desenvolver uma compreensão sobre os padrões de projeto de criação bem como os diferentes métodos de criação de objetos que ajudam a resolver problemas em desenvolvimento de software. Utilizar padrões de projeto estruturais e descobrir de que maneira os objetos e as classes interagem na construção de aplicações maiores. A interação entre os objetos com os padrões Command e Observer. Melhorar a produtividade e a base de código de sua aplicação usando padrões de projeto com Python.

Tire proveito da eficácia dos padrões de projeto (design patterns) em Python para resolver problemas do mundo real em arquitetura e design de software

Aprendendo Padrões de Projeto em Python

Leverage the power of Python design patterns to solve real-world problems in software architecture and design About This Book Understand the structural, creational, and behavioral Python design patterns Get to know the context and application of design patterns to solve real-world problems in software architecture, design, and application development Get practical exposure through sample implementations in Python v3.5 for the design patterns featured Who This Book Is For This book is for Software architects and Python application developers who are passionate about software design. It will be very useful to engineers with beginner level proficiency in Python and who love to work with Python 3.5 What You Will Learn Enhance your skills to create better software architecture Understand proven solutions to commonly occurring design issues Explore the design principles that form the basis of software design, such as loose coupling, the Hollywood principle and the Open Close principle among others Delve into the object-oriented programming concepts and find out how they are used in software applications Develop an understanding of Creational Design Patterns and the different object creation methods that help you solve issues in software development Use Structural Design Patterns and find out how objects and classes interact to build larger applications Focus on the interaction between objects with the command and observer patterns Improve the productivity and code base of your application using Python design patterns In Detail With the increasing focus on optimized software architecture and design it is important that software architects think about optimizations in object creation, code structure, and interaction between objects at the architecture or design level. This makes sure that the cost of software maintenance is low and code can be easily reused or is adaptable to change. The key to this is reusability and low maintenance in design patterns. Building on the success of the previous edition, Learning Python Design Patterns, Second Edition will help you implement real-world scenarios with Python's latest release, Python v3.5. We start by introducing design patterns from the Python perspective. As you progress through the book, you will learn about Singleton patterns, Factory patterns, and Facade patterns in detail. After this, we'll look at how to control object access with proxy patterns. It also covers observer patterns, command patterns, and compound patterns. By the end of the book, you will have enhanced your professional abilities in software architecture, design, and development. Style and approach This is an easy-to-follow guide to design patterns with hands-on examples of real-world scenarios and their implementation in Python v3.5. Each topic is explained and placed in context, and for the more inquisitive, there are more details on the concepts used.
