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.

Recent language additions

Every release of Python comes with it a lot of changes of different types. Almost every release of Python brings some new syntax elements. However, the majority of the changes are related to Python's standard library, the CPython interpreter, the Python API, and CPython's C API. Due to space limitations, it is impossible to cover all of these in this book. That is why we will focus just on new syntax features and new additions to the standard library.

In terms of the two latest versions of Python, we can distinguish four main syntax updates:

  • Dictionary and merge update operators (added in Python 3.9)
  • Assignment expressions (added in Python 3.8)
  • Type hinting generics (added in Python 3.9)
  • Positional-only arguments (added in Python 3.8)

These four features would best be described as quality-of-life improvements. They do not introduce any new programming paradigms, nor drastically change the way your code can...
