Attributes (Instance Variables): Variables that belong to an object. They store the data or state of the object. Attributes are typically defined within the __init__ method using self.attribute_name = value.

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

Methods: Functions that belong to a class. They define the behavior or actions that an object can perform. Methods always have self as their first parameter.

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

  def bark(self):  # Instance method
    print(f"{self.name} says Woof!")
