Python is a simple but powerful language, so it is used in a wide variety of areas. Writing code in Python is easy, but making it readable and reusable and maintainable can be a challenge. The fourth edition of this book is complemented by best practices, useful tools and standards that professional developers apply, which will help you not only overcome these difficulties, but also master the latest features and advanced concepts of the language. The book begins with a light warm-up, which will introduce you to the latest Python improvements, syntax elements and useful tools that make development more efficient. In addition, initial chapters will help programmers with experience in other languages ​ ​ successfully integrate into the Python ecosystem. The following chapters focus on common design patterns and programming methodologies - such as event-oriented programming, parallelism, and metaprogramming. You will also analyze complex code examples and solve meaningful problems by linking Python with C and C++ and creating extensions that combine the strengths of different languages.
