Data Types in Programming

Data types are an essential part of programming, providing a way to define the type of data that a variable can hold. Understanding data types is crucial for writing efficient and effective code.

Common Data Types

Integer: A whole number, without any decimal points. (e.g., 5, -3)
Float: A number with a decimal point. (e.g., 3.14, -2.5)
String: A sequence of characters, such as "Hello, World!". (e.g., "Hello", "Data Types")
Boolean: A true/false value. (e.g., True, False)

Data Types in Action

Here's an example of how data types are used in a simple Python program:

name = "John Doe"  # String
age = 30  # Integer
is_employee = True  # Boolean

print(f"My name is {name}, I am {age} years old, and I am an employee: {is_employee}.")

As you can see, we use different data types to store different types of information.
