Overview of this book

This new edition of Expert Python Programming provides you with a thorough understanding of the process of building and maintaining Python apps. Complete with best practices, useful tools, and standards implemented by professional Python developers, this fourth edition has been extensively updated. Throughout this book, you’ll get acquainted with the latest Python improvements, syntax elements, and interesting tools to boost your development efficiency. The initial few chapters will allow experienced programmers coming from different languages to transition to the Python ecosystem. You will explore common software design patterns and various programming methodologies, such as event-driven programming, concurrency, and metaprogramming. You will also go through complex code examples and try to solve meaningful problems by bridging Python with C and C++, writing extensions that benefit from the strengths of multiple languages. Finally, you will understand the complete lifetime of any application after it goes live, including packaging and testing automation. By the end of this book, you will have gained actionable Python programming insights that will help you effectively solve challenging problems.

The most important thing in developing software with TDD is always starting with tests. That's the only way you can ensure that code units are easily testable. This also naturally encourages good design practices like the single responsibility principle or the inversion of control. Sticking to those principles helps in writing good and maintainable code. And we've already seen how hard it is to test code reliably when tests are just an afterthought.

But caring about software correctness and maintainability does not end with testing and quality automation. These two allow us to verify the requirements we know about and fix bugs we have discovered. We can of course deepen the testing suite, and we've learned that mutation testing is an effective technique to discover potential testing blindspots, but this approach has its limits.

What follows next is usually the constant monitoring of the application and listening to bug reports submitted by the users...
