We will start by breaking down the syntax of the map() function and understanding how it applies a specific function to every item in an iterable (like a list). Then, we will look at lambda functions—short, one-line functions that make map() incredibly powerful without the need for defining full functions.

By the end of this tutorial, you will know how to replace clunky for loops with concise map/lambda one-liners.

In this video, you will learn:
✅ What is the map() function and how it works.
✅ How to create anonymous functions using lambda.
✅ Combining map() + lambda for efficient coding.
✅ Practical examples and comparisons with standard loops.
