Python for Programmers

Introduction

The book «Python for Programmers», written by Paul Deitel and Harvey Deitel, was published in 2019 and immediately earned a worthy place among educational materials on the Python language. The authors are recognized experts in the field of computer education, known for their «How to Program» book series. Unlike many introductory guides, this book is aimed at readers who already have programming experience in other languages (Java, C++, C#) and want to quickly and deeply master Python. The volume is 640 pages, which allows covering both the basics and advanced topics.

What the book is about

The book is built on the principle of «practice first, theory later». The authors do not waste time explaining basic programming concepts (loops, conditions, functions) — they immediately move on to the features of Python. The main focus is on:

• Syntax and idioms of Python 3 (list comprehensions, generators, decorators, context managers);
• Object-oriented programming in Python (classes, inheritance, polymorphism, magic methods);
• Working with data (strings, collections, files, serialization);
• Libraries for scientific computing and data analysis (NumPy, Pandas, Matplotlib);
• Web development (Flask, REST API, JSON);
• Databases (SQLite, MySQL);
• Multithreading and asynchrony (asyncio, threading);
• Testing (unittest, pytest) and debugging.

Each chapter contains many code examples that can be immediately run and modified. At the end of the chapters, there are exercises of varying difficulty levels.

Who this book is for

The main target audience is experienced developers who want to learn Python as a second or third language. If you already know what a variable, function, and class are, but are not familiar with Python — this book is for you. It will also be useful for senior students of technical specialties and teachers looking for structured material for a Python course.

What the reader will learn

• Write clean, idiomatic Python code;
• Use advanced language features (decorators, generators, context managers);
• Work with popular data analysis libraries;
• Create web applications with Flask;
• Handle errors and write tests;
• Understand the specifics of multithreading and asynchrony in Python;
• Integrate Python with databases and external APIs.

Strengths

• Practical focus: the book contains hundreds of code examples that can be immediately applied in work.
• Relevance: the material is based on Python 3.7–3.8, using modern libraries and approaches.
• Structure: logical chapter organization, from simple to complex, with clear headings and summaries.
• Depth: the authors are not afraid to delve into complex topics (metaclasses, descriptors, asyncio), but explain them accessibly.
• Code quality: all examples are tested, the code style conforms to PEP 8.

Who it is recommended for

The book will be useful for:

• Developers transitioning to Python from other languages;
• Students learning Python at university or independently;
• Teachers looking for a quality textbook for a course;
• Anyone who wants to deepen their Python knowledge and learn to write professional code.

If you are a beginner in programming, it is better to start with a more introductory book (for example, «Python Crash Course» or «Automate the Boring Stuff with Python»), and then return to «Python for Programmers» to deepen your knowledge.

Conclusion

«Python for Programmers» is an excellent textbook for those who already know how to program and want to quickly master Python at a professional level. The book is written in a lively language, contains many practical examples, and covers a wide range of topics — from
