Invent your own Python scripts to automate your infrastructure About This Book Make the most of Python libraries and modules to automate your infrastructure Leverage Python programming to automate server configurations and administration tasks Efficiently develop your Python skill set Who This Book Is For Hands-On Enterprise Automation with Python is for system administrators and DevOps engineers who are looking for an alternative to major automation frameworks such as Puppet and Chef. Basic programming knowledge with Python and Linux shell scripting is necessary. What You Will Learn Understand common automation modules used in Python Develop Python scripts to manage network devices Automate common Linux administration tasks with Ansible and Fabric Managing Linux processes Administrate VMware, OpenStack, and AWS instances with Python Security automation and sharing code on GitHub In Detail Hands-On Enterprise Automation with Python starts by covering the set up of a Python environment to perform automation tasks, as well as the modules, libraries, and tools you will be using. We'll explore examples of network automation tasks using simple Python programs and Ansible. Next, we will walk you through automating administration tasks with Python Fabric, where you will learn to perform server configuration and administration, along with system administration tasks such as user management, database management, and process management. As you progress through this book, you'll automate several testing services with Python scripts and perform automation tasks on virtual machines and cloud infrastructure with Python. In the concluding chapters, you will cover Python-based offensive security tools and learn how to automate your security tasks. By the end of this book, you will have mastered the skills of automating several system administration tasks with Python. Style and approach This book will follow a practical approach to help you script and automate tasks using Python.

Step-by-step recipes filled with practical code samples and engaging examples demonstrate Haskell in practice, and then the concepts behind the code. This book shows functional developers and analysts how to leverage their existing knowledge of Haskell specifically for high-quality data analysis. A good understanding of data sets and functional programming is assumed.

Gain a gentle introduction to the world of Ring programming with clarity as a first concern using a lot of practical examples. The first part lays the foundations of the language and its basic features (data types, control structures, functions, and classes). The unique way to rigorously structure Ring programs is also explained. Then, in the second part you’ll discover Ring inputs, outputs, and what is in between. You’ll use the basic constructs of computer logic (sequence, selection, and iteration) to build simple and complex logic flows. You’ll go over the common mistakes that lead to code complexity, by example, and cover several strategies to solve them (refactoring, code cleansing, and good variable naming). Then, you’ll see a visual illustration of how Ring deals with scopes at the local, object, and global levels. In part three, you’ll play with two artifacts vital to Ring programming: functions and objects. You’ll learn how they can be composed to solve a problem and how advanced programming paradigms, such as declarative and natural, are beautifully implemented on top of them. As part of the discussion, you’ll also work on game programming. You’ll learn how you design your game declaratively, in Ring code, just as if you were designing it in visual software. Finally, the author lays out how programming can be understood in a gamified context. You will be told the truth about how gaming can be a better metaphor to achieve mastery of Ring programming. This book is for those who are passionate about writing beautiful, expressive, and learnable code. It has been designed so you can enjoy a beginner-friendly set of knowledge about Ring, and benefit from a one-stop collection of lessons learned from real-world, customer-facing programming projects. You will: Get started with Ring and master its data types, I/O, functions, and classes Carry out structural, object-oriented, functional, declarative, natural, and meta programming in Ring Use the full power of Ring to refactor program code and develop clean program architectures Quickly design professional-grade video games on top of the Ring game engine.

Expert F# 3.0 is about practical programming in a beautiful language that puts the power and elegance of data-rich functional programming into the hands of professional developers. In combination with .NET, F# achieves unrivaled levels of programmer productivity and program clarity. Expert F# 3.0 is: A comprehensive guide to F# by the inventor of F# A treasury of F# techniques for practical problem-solving An in-depth case book of how F# applications and of F# 3.0 concepts, syntax, and features F# isn't just another functional programming language. It's a general-purpose language ideal for solving real-world development problems. F# seamlessly integrates functional, imperative, object-oriented and query programming styles so you can flexibly and elegantly solve any programming problem. F# 3.0 combines this with the seamless data-integration capabilities of F# Information-Rich Programming. Whatever your background, you’ll find that F# is easy to learn, fun to use, and extraordinarily powerful. F# will change the way you think about—and go about—programming. Written by F#'s inventor and two major F# community members, Expert F# 3.0 is a comprehensive and in-depth guide to the language and its use. Designed to help others become experts, the book quickly yet carefully describes the paradigms supported by F# language, and then shows how to use F# elegantly for a practical web, data, parallel and analytical programming tasks. The world's experts in F# show you how to program in F# the way they do!
