• Apply modules like functools and itertools effectively
• Structure programs using a functional approach
• Improve testability and reduce side effects in your code

Whether you're looking to adopt a functional style for specific parts of your projects or gain a deeper understanding of programming paradigms, this book offers practical examples and explanations tailored to Python programmers.
