Classes define blueprints for creating objects in object-oriented programming (OOP). Objects are instances of a class with attributes (data) and methods (functions) that perform specific tasks. OOP promotes structured, reusable, and maintainable code.

class ClassName:
  def __init__(self, attribute1, attribute2):
    self.attribute1 = attribute1
    self.attribute2 = attribute2

  def method_name(self, argument1):
    # do something
    return result

Example:

class Dog:
  def __init__(self, name, age):
    self.name = name
    self.age = age

  def bark(self):
    print("Woof!")

# Create an instance of Dog
dog1 = Dog("Buddy", 3)
dog1.bark()  # Output: Woof!
