Python Variables

Imagine you have a box where you can store anything you want — a number, a word, or even a whole sentence. In Python, we use something called a variable to store information like that!

What is a Variable?

A variable is like a label you stick on a box to remember what’s inside.

For example, you can create a variable called name and store your name in it:

name = "Alice"

Here, name is the variable, and "Alice" is the information we are saving inside it.

Another Example

Let's save a number in a variable:

age = 25

Now, the variable age holds the number 25.

How to Use Variables

After you create a variable, you can use it whenever you want. For example:

print(name)
print(age)

When you run this code, Python will show:

Alice
25

Important Rules for Naming Variables

• Names can only have letters, numbers, and underscores (_).
• Names cannot start with a number.
• Names should not have spaces. Use _ instead. (Example: my_age)
• Pick names that make sense! (Example: price is better than p.)

Summary

Variables help you save information in Python so you can use it later. You can store words, numbers, or other things — all by just giving them a name!
