Python Data Types Explained: Complete Beginner's Guide

 

Introduction

Python stores different kinds of information such as text, numbers, and true/false values. These different categories of data are called data types.

Understanding data types is important because they help Python know what kind of information is being stored and how it should be processed.

🤔 What Are Data Types in Python?

A data type defines the type of value a variable can store.

Example: name = "Shivuu", age = 19

Here:

• name is a String
• age is an Integer

🔤 String Data Type (str)

A string stores text.

name = "Python"

Examples:

• Names
• Addresses
• Messages

🔢 Integer Data Type (int)

Integers store whole numbers.

age = 19 

marks = 95

Examples:

• Age
• Number of students
• Roll numbers

📊 Float Data Type (float)

Floats store decimal numbers.

price = 99.99

 height = 5.8

Examples:

• Prices
• Measurements
• Percentages

✅ Boolean Data Type (bool)

Boolean values can only be:

True, False

is_student = True

Used in:

• Conditions
• Decision making
• Login system

🧪 Checking Data Types

Python provides the type() function.

name = "Python" 

 print(type(name))

Output:  <class 'str'>

🎯 Why Are Data Types Important?

Data types help programmers:

• Store information correctly
• Avoid errors
• Perform calculations
• Write efficient programs

⚠️ Common Beginner Mistakes

Mistake 1

age = "19"

This is a String, not an Integer.
Correct
age = 19
