Mak R. Software Design for Python Programmers. Principles and patterns 2026

Textbook in PDF format Design principles and patterns for building better Python software. Software Design for Python Programmers shows you how to level up from writing Python code to designing Python applications. Following intuitive “before” and “after” examples of improved code, you’ll learn to plan and execute Python applications effectively and avoid bugs associated with unmanaged state, poorly-formed classes, inflexible functions, and more. In Software Design for Python Programmers, you’ll learn how to: Analyze requirements and plan application architecture Evolve designs through iterative development Shape Python classes with high cohesion and loose coupling Use decorators to introduce abstraction, enforce constraints, and enrich behavior Apply industry-standard design principles to keep code modular and maintainable Choose and implement the right design patterns for complex challenges Great applications take advantage of established design principles and patterns that maximize performance, maintainability, and reliability. This book helps you master the “Pythonic” approach to architectural principles, such as encapsulation, abstraction, method variation, and more. The examples are in Python, but the techniques will apply to any object-oriented language. Working with students and other beginning programmers has taught me that it’s important to practice good software design before bad habits set in. As students, we inadvertently learn “run and done”: as soon as a program assignment runs successfully, it’s done! After we turn it in, we may never have to see it again, so good design concepts such as maintainability are immaterial. We must unlearn that mentality to have a successful career as a professional software developer. I am well aware of the pressures to get an application done on time and under budget. Therefore, I teach an iterative, incremental approach to software development. If we can’t reach the last iteration and complete the product due to an upcoming deadline, we want the results of the next-to-last iteration (or the next-to-next-to-last iteration) to produce a minimum viable product (MVP). Well-designed applications can actually take less time to develop. Hopefully there will be the next release of the application to clean up design problems and add more features. about the technology Great software starts with thoughtful design. You’ll be a more effective developer if you can decide how data will flow through your applications, create a winning software architecture, and structure functions, classes, and modules before you write a line of code. This book will get you started! about the book Software Design for Python Programmers is a practical guide for creating maintainable, well-structured software in Python. By investigating clear “before and after” examples, you’ll discover how even small design choices can have a huge impact on an application’s clarity and reliability. As you go, you’ll learn how to gather requirements, shape a program’s architecture iteratively, create clean and reusable abstractions, and select design patterns that solve the real problems you’ll face on the job. about the reader For programmers comfortable with Python syntax
