Expert Python Programming - Third Edition

By: Michał Jaworski, Tarek Ziadé

Overview of this book

Python is a dynamic programming language that's used in a wide range of domains thanks to its simple yet powerful nature. Although writing Python code is easy, making it readable, reusable, and easy to maintain is challenging. Complete with best practices, useful tools, and standards implemented by professional Python developers, the third edition of Expert Python Programming will help you overcome this challenge. The book will start by taking you through the new features in Python 3.7. You'll then learn the advanced components of Python syntax, in addition to understanding how to apply concepts of various programming paradigms, including object-oriented programming, functional programming, and event-driven programming. This book will also guide you through learning the naming best practices, writing your own distributable Python packages, and getting up to speed with automated ways to deploy your software on remote servers. You’ll discover how to create useful Python extensions with C, C++, Cython, and CFFI. Furthermore, studying about code management tools, writing clear documentation, and exploring test-driven development will help you write clean code. By the end of the book, you will have become an expert in writing efficient and maintainable Python code.

Isolating the runtime environment

pip may be used to install system-wide packages. On UNIX-based and Linux systems, this will require superuser privileges, so the actual invocation will be as follows:

sudo pip install <package-name>

Note that this is not required on Windows since it does not provide the Python interpreter by default, and Python on Windows is usually installed manually by the user without superuser privileges.

Installing system-wide packages directly from PyPI is not recommended, and should be avoided. This may seem like a contradiction to the previous statement that using pip is a PyPA recommendation, but there are some serious reasons for that. As we explained earlier, Python is often an important part of many packages that are available through operating system package repositories, and may power a lot of important services.
