Python From Scratch Lesson 12 PDF (Python Functions & Lambda)

Welcome to the twelfth lesson of the “Python From Scratch” series! In this lesson, we will be exploring one of the most powerful concepts in programming – functions. Functions are blocks of reusable code that can be called from anywhere in a program, making them incredibly useful for organizing code and reducing redundancy.

We will begin by learning the basics of functions, including how to create them, pass arguments, and return values. We will also cover more advanced topics, such as default arguments, variable-length argument lists, and recursion. In addition to regular functions, we will also explore lambda functions, which are a type of anonymous function that can be created on the fly and used in a variety of contexts.

Throughout this lesson, we will be building on the knowledge and skills that we have developed in previous lessons, so it is recommended that you have a solid understanding of Python fundamentals before diving into this one. However, even if you are new to Python, you should be able to follow along with the examples and exercises provided.
