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.

Chapter 1. Current Status of Python

Python is good for developers.

No matter what operating system you or your customers are running, it will work. Unless you are coding platform-specific things, or using a platform-specific library, you can work on Linux and deploy on other systems, for example. However, that's not uncommon anymore (Ruby, Java, and many other languages work in the same way). Combined with the other qualities that we will discover throughout this book, Python becomes a smart choice for a company's primary development language.

This book is focused on the latest version of Python, 3.5, and all code examples are written in this version of the language unless another version is explicitly mentioned. Because this release is not yet widely used, this chapter contains some description of the current status quo of Python 3 to introduce readers to it, as well as some introductory information on modern approaches to development in Python. This chapter covers the following topics:

  • How to maintain compatibility between Python 2 and Python 3
  • How to approach the problem of environment isolation both on application and operating system level for the purpose of development
  • How to enhance the Python prompt
  • How to install packages using pip

A book always starts with some appetizers. So, if you are already familiar with Python (especially with the latest 3.x branch) and know how to properly isolate environments for development purposes, you can skip the first two sections of this chapter and just read the other sections quickly. They describe some tools and resources that are not essential but can highly improve productivity in Python. Be sure to read the section on application-level environment isolation and pip, though, as their installation is mandatory for the rest of the book.
