Python Functions Explained: Regular Functions and Lambda Functions for Beginners

In this video, we dive into one of the most essential concepts in Python programming: functions. Whether you're new to coding or brushing up on your skills, understanding how functions work is key to writing clean, reusable, and efficient code.

We start with the basics of defining functions using the def keyword, covering syntax, parameters, return values, and how to call functions. You’ll learn why functions are important for structuring your code, reducing repetition, and improving readability.

Next, we explore function arguments, including positional arguments, keyword arguments, default values.

Then we introduce lambda functions, also known as anonymous functions. You'll see how lambda expressions provide a concise way to define small, one-line functions without using def. We compare regular functions and lambda functions, and show you where lambda functions are most useful.

By the end of the video, you’ll have a solid understanding of:
✔️ How to create and use functions in Python
✔️ When to use regular vs. lambda functions
✔️ Common use cases for lambda expressions in real-world code
