Description

Not enough developers understand the benefits of functional programming, or even what it is. Author Steven Lott demystifies the approach, teaching you how to improve the way you code in Python and make gains in memory use and performance. If you’re a leetcoder preparing for coding interviews, this book is for you. Starting from the fundamentals, this book shows you how to apply functional thinking and techniques in a range of scenarios, with Python 3.10+ examples focused on mathematical and statistical algorithms, data cleaning, and exploratory data analysis. You'll learn how to use generator expressions, list comprehensions, and decorators to your advantage. You don't have to abandon object-oriented design completely, though – you'll also see how Python's native object orientation is used in conjunction with functional programming techniques. By the end of this book, you'll be well-versed in the essential functional programming features of Python and understand why and when functional thinking helps. You'll also have all the tools you need to pursue any additional functional topics that are not part of the Python language.

Who is this book for?

The functional paradigm is very useful for programmers working in data science or preparing for technical interviews, but any Python developer who wants to create more reliable, succinct, and expressive code will have much to learn from this book. No prior knowledge of functional programming is required to get started, though Python programming knowledge is assumed. A running Python environment is essential.

What you will learn

Use Python's libraries to avoid the complexities of state-changing classes

Leverage built-in higher-order functions to avoid rewriting common algorithms

Write generator functions to create lazy processing

Design and implement decorators for functional composition

Make use of Python type annotations to describe parameters and results of functions

Apply functional programming to concurrency and web services

Explore the PyMonad library for stateful simulations

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

This Book strengthened my ability to exploit pythons facilities for functional programming. Taking a more functional approach sometimes you can get a lot more done. Then when you combine that with the OOP is a whole new world!

This book explains excellent explanation on functional programming concept. This book is not intended for beginner students. For anyone who wants to read this book must have solid python understanding and working experience.The author covered functional programming with python for almost all the major topics in programming such as multi threading and also other topics such as web services which gives an excellent insight on how to use functional programming with python. The exercises are also good which gives good insight on some of the edge case problems. Overall it's an excellent read for an experienced programmer.

The book provides a smooth introduction to the world of functional programming. It illustrates the core concepts of functional programming (like high-order functions, decorators, generators and iterators) and shows how it’s possible to leverage standard library modules (like IterTools and FuncTools, for instance) to simplify the task of writing functional code. The book has plenty of code samples (which are available on GitHub) that make it really easy to understand and follow the content. I would highly recommend it to anybody looking to familiarize themselves with functional programming.My personal book highlights are:✔️ Higher-Order Functions✔️ Decorator Design Techniques✔️ The Multiprocessing, Threading, and Concurrent.Futures Modules✔️ A Functional Approach to Web Services

This book covers many important topics for functional programming in python from intermediate to advanced levels. Both junior (with some python basis) and senior readers can find useful information from the book. As well, this book also provides good examples for readers.
