📘 Day 10: Lambda Functions in Python — The Power of One-Liners! ⚡

 Hey Pythonista! 🐍

Today, we're diving into something short, sweet, and surprisingly powerful — Lambda Functions. These are tiny, anonymous functions that you can write in a single line.

                                

                                            

🔹 What is a Lambda Function?

          A lambda function is a small anonymous function that can have any number of arguments but only one expression.

🧪 Example 1: Add Two Numbers

                                        

🧪 Example 2: Square a Number

                                         

📍 Why Use Lambda Functions?

• Used for short, throwaway functions

• Often used with map(), filter(), and sorted()

• Keeps your code clean and concise

🧰 Use with map()




                   

🧰 Use with filter()




                    


Lambda functions are:

• Single-expression only (no multiple lines or statements)

• Great for quick jobs, but not for complex logic

🧠 Mini Practice

Try these:

1. Write a lambda to multiply 3 numbers.

2. Filter words starting with 'a' from a list using filter().

✍️ Your Turn!

Have you ever seen or used a lambda in real-world code? Try converting a regular function into a lambda and see the difference!

Keep this in mind:

                          "A function is like a recipe — define it once, reuse it forever." 🧠🍳
