Python Variables Explained for Beginners (With Simple Examples)

By Ayush Gupta

Introduction

In our previous posts, we learned how to install Python and how to write our first program. Now it’s time to understand one of the most important concepts in Python — Variables.

This post is written for absolute beginners, so don’t worry if you have never coded before.

What is a Variable?

A variable is used to store data in a program. You can think of a variable as a container that holds a value.

Variable = Name given to a memory location where data is stored.

Creating a Variable in Python

In Python, creating a variable is very easy. You don’t need to mention any data type.

x = 10

Here:

• x → variable name
• = → assignment operator
• 10 → value stored

---

Printing a Variable

To display the value stored inside a variable, we use the print() function.

x = 10
print(x)

Output:

10

Variables Can Store Different Types of Data

1️⃣ Integer (Whole Numbers)

age = 21

2️⃣ Float (Decimal Numbers)

price = 99.50

3️⃣ String (Text)

name = "Ayush"

---

Changing the Value of a Variable

The value of a variable can be changed anytime.

x = 5
x = 20
print(x)

Output:

20

Rules for Naming Variables

• Must start with a letter or underscore
• Cannot start with a number
• No spaces allowed
• Python is case-sensitive

Valid: name, _value, totalMarks
Invalid: 1name, total marks

---

Multiple Variables in One Line

a, b, c = 1, 2, 3
print(a)
print(b)
print(c)

---

Why Variables Are Important?

• Store user input
• Perform calculations
• Reuse data
• Make programs dynamic
