By taking you through the development of a real web application from beginning to end, the second edition of this hands-on guide demonstrates the practical advantages of test-driven development (TDD) with Python. You’ll learn how to write and run tests before building each part of your app, and then develop the minimum amount of code required to pass those tests. The result? Clean code that works. In the process, you’ll learn the basics of Django, Selenium, Git, jQuery, and Mock, along with current web development techniques. If you’re ready to take your Python skills to the next level, this book—updated for Python 3.6—clearly demonstrates how TDD encourages simple designs and insp...
As Python continues to grow in popularity, projects are becoming larger and more complex. Many Python developers are now taking an interest in high-level software design patterns such as hexagonal/clean architecture, event-driven architecture, and the strategic patterns prescribed by domain-driven design (DDD). But translating those patterns into Python isn’t always straightforward. With this hands-on guide, Harry Percival and Bob Gregory from MADE.com introduce proven architectural design patterns to help Python developers manage application complexity—and get the most value out of their test suites. Each pattern is illustrated with concrete examples in beautiful, idiomatic Python, avoiding some of the verbosity of Java and C# syntax. Patterns include: Dependency inversion and its links to ports and adapters (hexagonal/clean architecture) Domain-driven design’s distinction between entities, value objects, and aggregates Repository and Unit of Work patterns for persistent storage Events, commands, and the message bus Command-query responsibility segregation (CQRS) Event-driven architecture and reactive microservices
Embracing the unexpected can lead to all sorts of adventures. The prophesied time has arrived and Harry—born of an alien mother and a human father - must journey to the top of the world to unlock a mysterious ship found trapped in an icy crevasse. A ship only someone of Harry’s bloodline can open. Roshin, a young Alvian scribe, is sent to record events as they unfold. Beneath her remote, icy beauty, Harry feels an unwanted hum of attraction. He has always dreamed of a warm, giving relationship with a human. Not a cold, emotionless Alvian. Then there’s Cormac, an Alvian officer sent to head the expedition. When all three are trapped inside the vessel, Harry is confronted with an unexpected dilemma - cling to his dream of a human bond, or answer the call of fate and form a lifelong alliance with not just one, but two aliens.
Scholars have long known that early American women wrote pious, sentimental stories. This book uses biographical and archival sources to understand how their religious concerns fed into debates about democracy and belief in a republic, and offers a new account of their political participation and the process of religious disestablishment.
Beginning with an introduction that examines the portrayal of the characters of Lancelot and Guinevere from their origins to the present day, this collection of 16 essays-five of which appear here for the first time-puts particular emphasis on the appearance of the two characters in medieval and modern literature. Besides several studies exploring feminist concerns, the volume features articles on the representation of the lovers in medieval manuscript illuminations (18 plates focus on scenes of their first kiss and the consummation of the adultery), in film, and in other visual arts. A 200-item bibliography completes the volume.
