Day 9: Mastering Lambda, Map & Filter in Python | Hands-on Practice

-- **Description:**

Welcome to **Day 9 of Python Learning Series**!
In this session, we dive into powerful functional programming tools in Python – **`lambda` functions**, **`map()`**, and **`filter()`**. With real-world examples and beginner-friendly questions, you'll learn how to simplify code using these essential tools.

💡 Practice Questions Included:

* Create and use lambda functions
* Use `map()` to transform data
* Use `filter()` to extract specific data
* Mini project: Bulk Salary Raise using map and lambda

Ideal for beginners who want to make their Python code more concise and efficient.
