Python: Master the Art of Design Patterns

Overview of this book

Python is an object-oriented scripting language that is used in everything from data science to web development. Known for its simplicity, Python increases productivity and minimizes development time. Through applying essential software engineering design patterns to Python, Python code becomes even more efficient and reusable from project to project. This learning path takes you through every traditional and advanced design pattern best applied to Python code, building your skills in writing exceptional Python. Divided into three distinct modules, you’ll go from foundational to advanced concepts by following a series of practical tutorials. Start with the bedrock of Python programming – the object-oriented paradigm. Rethink the way you work with Python as you work through the Python data structures and object-oriented techniques essential to modern Python programming. Build your confidence as you learn Python syntax, and how to use OOP principles with Python tools such as Django and Kivy. In the second module, run through the most common and most useful design patterns from a Python perspective. Progress through Singleton patterns, Factory patterns, Façade patterns and more all with detailed hands-on guidance. Enhance your professional abilities in in software architecture, design, and development. In the final module, run through the more complex and less common design patterns, discovering how to apply them to Python coding with the help of real-world examples. Get to grips with the best practices of writing Python, as well as creating systems architecture and troubleshooting issues. This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products: ? Python 3 Object-Oriented Programming - Second Edition by Dusty Phillips ? Learning Python Design Patterns - Second Edition by Chetan Giridhar ? Mastering Python Design Patterns by Sakis Kasampalis

Chapter 11. AntiPatterns

In the previous chapter, we started with an introduction to Compound patterns. You learned how design patterns work together to solve a real-world design problem. We went further to explore the Model-View-Controller design pattern—the king of Compound patterns. We understood that the MVC pattern is used when we need loose coupling between components and separation of the way in which data is stored from the way data is presented. We also went through the UML diagram of the MVC pattern and read about how the individual components (model, view, and controller) work among themselves. We also saw how it's applied in the real world with the help of the Python implementation. We discussed the benefits of the MVC pattern, learned more about it in the FAQs section, and summarized the discussion at the end of chapter.

In this chapter, we will talk about AntiPatterns. This is different from all the other chapters in the book; here, we will cover what...
