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.

Implementing the singleton pattern

The singleton pattern offers a way to implement a class from which you can only create one object, hence the name singleton. As you will understand with our exploration of this pattern, or while doing your own research, there have always been discussions about this pattern, and some even consider it an anti-pattern.

Besides that, what is interesting is that it is useful when we need to create one and only one object, for example, to store and maintain a global state for our program. In Python, this pattern can be implemented using some special built-in features.

The singleton pattern restricts the instantiation of a class to one object, which is useful when you need one object to coordinate actions for the system.

The basic idea is that only one instance of a particular class is created for the needs of the program. To ensure that this works, we need mechanisms that prevent the instantiation of the class more than once and also prevent cloning...
