Overview of this book

This Learning Path shows you how to leverage the power of both native and third-party Python libraries for building robust and responsive applications. You will learn about profilers and reactive programming, concurrency and parallelism, as well as tools for making your apps quick and efficient. You will discover how to write code for parallel architectures using TensorFlow and Theano, and use a cluster of computers for large-scale computations using technologies such as Dask and PySpark. With the knowledge of how Python design patterns work, you will be able to clone objects, secure interfaces, dynamically choose algorithms, and accomplish much more in high performance computing. By the end of this Learning Path, you will have the skills and confidence to build engaging models that quickly offer efficient solutions to your problems. This Learning Path includes content from the following Packt products: • Python High Performance - Second Edition by Gabriele Lanaro • Mastering Concurrency in Python by Quan Nguyen • Mastering Python Design Patterns by Sakis Kasampalis

Chapter 26. The Adapter Pattern

In the previous chapters, we have covered creational patterns, object-oriented programming patterns that help us with object creation procedures. The next category of patterns we want to present is structural design patterns.

A structural design pattern proposes a way of composing objects for creating new functionality. The first of these patterns we will cover is the adapter pattern.

The adapter pattern is a structural design pattern that helps us make two incompatible interfaces compatible. What does that really mean? If we have an old component and we want to use it in a new system, or a new component that we want to use in an old system, the two can rarely communicate without requiring any code changes. But, changing the code is not always possible, either because we don't have access to it, or because it is impractical. In such cases, we can write an extra layer that makes all the required modifications for enabling the communication between the two interfaces...
