What Are Variables in Programming? Digital Containers?

Variables are how computers remember things.
They’re like labeled containers that hold information and you get to decide what goes inside.

What Is a Variable?

A variable is a name you assign to a value. It could be a number, a word, or even a list of things.
Here’s a simple example in Python:

name = "YourName"
age = 67

Now the computer knows that name refers to "YourName" and age refers to 67.

Why Variables Matter

• They help you store and reuse information
• They make your code readable and flexible
• They’re essential for logic, automation, and decision-making

Try This

greeting = "Hello"
name = "world"
print(greeting + ", " + name + "!")

This combines two variables to create a message:
Hello, world!

Real-Life Analogy

Imagine labeling jars in your kitchen:

• sugar = white crystals
• salt = tiny grains
• tea = dried leaves

You don’t need to remember what’s inside; the label does it for you.
