Fluent Python; Clear, Concise, and Effective Programming 2nd Edition

Stop forcing Python to follow patterns from other programming languages. Python’s strength lies in its simplicity and expressive power—but to truly take advantage of it, you need to go beyond the basics. This newly updated edition of Luciano Ramalho’s hands-on guide shows you how to write clean, modern Python 3 code by embracing the language’s most effective and idiomatic features.

Whether you're a seasoned developer or transitioning from another language, this book helps you deepen your understanding of Python’s core design philosophies. Ramalho walks you through Python’s built-in capabilities and libraries, demonstrating how to write code that is not only more concise and readable, but also faster and more maintainable.

This comprehensive second edition is organized into five self-contained parts—each functioning like a short book of its own:

• Data Structures: Explore sequences, dictionaries, sets, Unicode handling, and data classes

• Functions as Objects: Learn about first-class functions, function-based design patterns, and the use of type hints

• Object-Oriented Idioms: Dive into composition, inheritance, mixins, interfaces, operator overloading, protocols, and static typing

• Control Flow: Master tools like context managers, generators, coroutines, async/await syntax, and concurrency via thread and process pools

• Metaprogramming: Understand advanced features like properties, descriptors, class decorators, and updated class metaprogramming hooks that streamline or replace metaclasses

Perfect for developers who want to write idiomatic and efficient Python, this guide will help you level up your Python skills and rethink the way you write code.
