Welcome to our Python Programs for Beginners series!
In this video, you'll learn how to check whether a number is even or odd using the Bitwise AND Operator (&) in Python.

Instead of using the traditional modulus operator, we’ll explore a faster and more efficient technique using bitwise operations. You’ll see how binary patterns help us quickly determine if a number is even or odd based on its last bit.

👨‍🏫 In This Video, You'll Learn:

What are even and odd numbers?

How even and odd numbers look in binary format

Why even numbers end with 0 and odd numbers end with 1 in binary

How the Bitwise AND Operator works at the binary level

Writing a Python program using n & 1 condition

Performing a dry run with real examples (10 and 9)

🧠 Concept Recap:

n & 1 == 0 → Even number

n & 1 == 1 → Odd number

📌 Example Outputs:

Input: 10 → Output: The number is even

Input: 9 → Output: The number is odd

Whether you're a beginner or just brushing up on bitwise logic, this tutorial is a simple and clear introduction to binary-level operations in Python.
