Classes and Objects

A class is a blueprint for creating objects. An object is an instance of a class.

Basic Class Structure

class Dog:
    def __init__(self, name, age):
        self.name = name
        self.age = age
Create an object
my_dog = Dog("Buddy", 3)
print(my_dog.name)  # Buddy

Key Concepts

• __init__ is the constructor method
• self refers to the current instance
• Attributes store data about the object

Your Task

Create a class called Expense with:

• An __init__ method that takes description and amount
• Store both as instance attributes

Create an expense and print its description and amount.
