Overview of this book

Python's powerful capabilities for implementing robust and efficient programs make it one of the most sought-after programming languages. In this book, you'll explore the tools that allow you to improve performance and take your Python programs to the next level. This book starts by examining the built-in as well as external libraries that streamline tasks in the development cycle, such as benchmarking, profiling, and optimizing. You'll then get to grips with using specialized tools such as dedicated libraries and compilers to increase your performance at number-crunching tasks, including training machine learning models. The book covers concurrency, a major solution to making programs more efficient and scalable, and various concurrent programming techniques such as multithreading, multiprocessing, and asynchronous programming. You'll also understand the common problems that cause undesirable behavior in concurrent programs. Finally, you'll work with a wide range of design patterns, including creational, structural, and behavioral patterns that enable you to tackle complex design and architecture challenges, making your programs more robust and maintainable. By the end of the book, you'll be exposed to a wide range of advanced functionalities in Python and be equipped with the practical knowledge needed to apply them to your use cases.

Implementation

Let's assume we are building an application where the user is going to manage and deliver content after fetching it from diverse sources, which could be the following:

  • A web page (based on its URL)
  • A resource accessed on an FTP server
  • A file on the local filesystem
  • A database server

So, here is the idea: instead of implementing several content classes, each holding the methods responsible for getting the content pieces, assembling them, and showing them inside the application, we can define an abstraction for the Resource Content and a separate interface for the objects that are responsible for fetching the content. Let's try it!

We begin with the class for our Resource Content abstraction, called ResourceContent. Then, we will need to define the interface for implementation classes that help fetch content, that is, the ResourceContentFetcher class. This concept is called the Implementor.

The first trick we use here is to use...
