Overview of this book

Python is a dynamic programming language, used in a wide range of domains by programmers who find it simple, yet powerful. Even if you find writing Python code easy, writing code that is efficient and easy to maintain and reuse is a challenge. The focus of the book is to familiarize you with common conventions, best practices, useful tools and standards used by python professionals on a daily basis when working with code. You will begin with knowing new features in Python 3.5 and quick tricks for improving productivity. Next, you will learn advanced and useful python syntax elements brought to this new version. Using advanced object-oriented concepts and mechanisms available in python, you will learn different approaches to implement metaprogramming. You will learn to choose good names, write packages, and create standalone executables easily. You will also be using some powerful tools such as buildout and vitualenv to release and deploy the code on remote servers for production use. Moving on, you will learn to effectively create Python extensions with C, C++, cython, and pyrex. The important factors while writing code such as code management tools, writing clear documentation, and test-driven development are also covered. You will now dive deeper to make your code efficient with general rules of optimization, strategies for finding bottlenecks, and selected tools for application optimization. By the end of the book, you will be an expert in writing efficient and maintainable code.

The Twelve-Factor App


The main requirement for painless deployment is building your application in a way that ensures that this process will be simple and as streamlined as possible. This is mostly about removing obstacles and encouraging well-established practices. Following such common practices is especially important in organizations where only specific people are responsible for development (developers team or Dev for short) and different people are responsible for deploying and maintaining the execution environments (operations team or Ops for short).

All tasks related to server maintenance, monitoring, deployment, configuration, and so on are often put to one single bag called operations. Even in organizations that have no separate teams for operational tasks, it is common that only some of the developers are authorized to do deployment tasks and maintain the remote servers. The common name for such a position is DevOps. Also, it isn't such an unusual situation that every member of...
