Variables and Data Types

Welcome to the world of Python! Today, we'll learn about variables and the different types of data you can use in your programs.

What is a Variable?

A variable is like a labeled box that holds information. You can use variables to store numbers, words, and more, making it easier to work with data in your programs.

Creating a Variable

To create a variable in Python, you just need to give it a name and assign a value to it using the equals sign (=).

Example of a Variable

Let's look at some examples of variables in Python:

message = "Hello, Python!"
number = 10
pi = 3.14

Data Types in Python

Data types tell Python what kind of information you're working with. Let's explore the most common ones:

• String (str): Text enclosed in quotes.
• Integer (int): Whole numbers without decimals.
• Float (float): Numbers with decimals.

Strings

Strings are used to store text. You can create a string by enclosing characters in single (') or double (") quotes.

Here are some examples:

greeting = "Hello, World!"
name = 'Alice'

Integers

Integers are whole numbers without any decimal points. They can be positive or negative.

Examples of integers:

age = 15
score = -10
year = 2024

Floats

Floats are numbers that have decimal points. They allow you to represent more precise values.

Here are some examples of floats:

temperature = 36.6
price = 19.99
distance = 3.14

Putting It All Together

Let's see how variables and data types work together in a simple program.

Here's an example:

# Storing different types of data
name = "Bob"
age = 12
height = 1.75

# Displaying the information
print("Name:", name)
print("Age:", age)
print("Height:", height, "meters")
