While readers must understand the basics of Python programming, no knowledge of modular programming techniques is required.What You Will Learn·Learn how to use modules and packages to organize your Python code·Understand how to use the import statement to load modules and packages into your program·Use common module patterns such as abstraction and encapsulation to write better programs·Discover how to create self-testing Python packages·Create reusable modules that other programmers can use·Learn how to use GitHub and the Python Package Index to share your code with other people·Make use of modules and packages that others have written·Use modular techniques to build robust systems that can handle complexity and changing requirements over timeIn DetailPython has evolved over the years and has become the primary choice of developers in various fields. The purpose of this book is to help readers develop readable, reliable, and maintainable programs in Python.Starting with an introduction to the concept of modules and packages, this book shows how you can use these building blocks to organize a complex program into logical parts and make sure those parts are working correctly together.Using clearly written, real-world examples, this book demonstrates how you can use modular techniques to build better programs. A number of common modular programming patterns are covered, including divide-and-conquer, abstraction, encapsulation, wrappers and extensibility. You will also learn how to test your modules and packages, how to prepare your code for sharing with other people, and how to publish your modules and packages on GitHub and the Python Package Index so that other people can use them. Finally, you will learn how to use modular design techniques to be a more effective programmer.Style and approachThis book will be simple and straightforward, focusing on imparting learning through a wide array of examples that the readers can put into use as they read through the book. They should not only be able to understand the way modules help in improving development, but they should also be able to improvise on their techniques of writing concise and effective code.

As with any enterprise involving violence and lots of money, running a plantation in early British America was a serious and brutal enterprise. Beyond resources and weapons, a plantation required a significant force of cruel and rapacious men-men who, as Trevor Burnard sees it, lacked any better options for making money. In the contentious Planters, Merchants, and Slaves, Burnard argues that white men did not choose to develop and maintain the plantation system out of virulent racism or sadism, but rather out of economic logic because-to speak bluntly-it worked.These economically successful and ethically monstrous plantations required racial divisions to exist, but their successes were always measured in gold, rather than skin or blood. Burnard argues that the best example of plantations functioning as intended is not those found in the fractious and poor North American colonies, but those in their booming and integrated commercial hub, Jamaica. Sure to be controversial, this book is a major intervention in the scholarship on slavery, economic development, and political power in early British America, mounting a powerful and original argument that boldly challenges historical orthodoxy.
