# Python for Beginners: Part 3 - Exploring Data Types

## Numbers, Text, and More

Welcome back, everyone! Today, we're going to dive a little deeper into the world of Python programming by exploring data types. Just like different tools for building a house have different uses and purposes, data types in Python help us organize and work with different kinds of information. So, let's get with Python data types!

**Understanding Data Types**

In Python, there are several primary data types we use to represent different kinds of information. Let's explore three common data types: numbers, text, and boolean.

**1. Numbers**

Numbers in Python can be of two types: integers (whole numbers) and floating-point numbers (numbers with decimal points). Here are some examples:

Integer: 7, 15, 42

Floating-Point: 3.14, 2.5, 0.5

We can perform mathematical operations on numbers, such as addition, subtraction, multiplication, and division. Let's take a look at an example:

```
# Performing arithmetic operations
x = 10
y = 4
addition = x + y
subtraction = x - y
multiplication = x * y
division = x / y
# Displaying the results
print("Addition:", addition)
print("Subtraction:", subtraction)
print("Multiplication:", multiplication)
print("Division:", division)
```

**2. Text (Strings)**

Text in Python is represented by a data type called a string. Strings are enclosed in single quotes ('') or double quotes (""). Here are some examples:

"Hello, world!"

'Python is fun!'

"I'm learning coding."

We can perform various operations on strings, such as concatenation (joining strings together) and accessing individual characters. Let's see an example:

```
# Working with strings
name = "Alice"
greeting = "Hello, " + name + "!"
character = name[0] # Accessing the first character of the name
# Displaying the results
print(greeting)
print("The first character of my name is:", character)
```

**3. Boolean**

Boolean data type represents truth values: either true or false. Booleans are often used in decision-making and control structures. Here are some examples:

True

False

We can use comparison operators to compare values and obtain boolean results. Let's see an example:

```
# Working with booleans
x = 5
y = 10
is_greater = x > y
is_equal = x == y
# Displaying the results
print("Is x greater than y?", is_greater)
print("Is x equal to y?", is_equal)
```

**Conclusion**

Congratulations, young coders! You've learned about different data types in Python: numbers, text (strings), and booleans. You've seen how we can perform operations on numbers, manipulate strings, and use booleans for decision-making.

Data types are like building blocks that help us work with various types of information in our programs. In the next post, we'll continue our coding journey by exploring loops, a powerful concept that allows us to repeat actions.

Stay curious and keep coding!
