Chapter 7 Class 11 - Functions

Do you want to learn how to create and use functions in Python? Do you want to learn how to make your code more modular, reusable and readable? Do you want to explore the concepts of scope, parameters, return values, recursion and lambda expressions in Python? If you answered yes to any of these questions, then this chapter is for you! 🙌

In this chapter, you will learn the details and applications of functions in Python programming and how to use them for various purposes. You will learn how to:

• Define and call your own functions using the def and return keywords 📝
• Use positional, keyword, default and variable-length arguments to pass parameters to functions 📦
• Use global and nonlocal keywords to modify the scope and visibility of variables inside and outside functions 🛠️
• Use recursion to solve problems that can be broken down into smaller subproblems 🎯
• Use lambda expressions to create anonymous functions that can be passed as arguments or returned as values 🚀
• Use built-in functions such as map, filter, reduce and sorted to apply functions to iterables and produce new results 🗃️
• Use modules and libraries to import and use external functions and resources 📚

By the end of this chapter, you will have a thorough understanding of how to create and use functions in Python and make your code more efficient and elegant. You will also be able to apply your function skills to various domains such as mathematics, science, engineering, games, art and more. 😍

This chapter is designed for students who have some basic knowledge of Python programming and flow control, but want to learn more about functions and their applications. It is also suitable for anyone who is interested in learning more about Python and its features. 🚀
