Class Hierarchy
Animal (Parent)
Dog (Child)
Animal (Parent Class)
name, speak()
Dog (Child Class)
breed, speak() (inherited), bark()
Basic Inheritance Example
class Animal:
def __init__(self, name):
self.name = name
def speak(self):
return f"{self.name} makes a sound"

class Dog(Animal):  # Basic inheritance
def __init__(self, name, breed):
super().__init__(name)
self.breed = breed
def bark(self):
return f"{self.name} barks"
Instance Creation
# Create instance
my_dog = Dog("Buddy", "Golden Retriever")

# Test inheritance
print(f"Parent attribute: {my_dog.name}")
print(f"Child attribute: {my_dog.breed}")
print(my_dog.speak())
print(my_dog.bark())
Method Execution
my_dog.speak() called
Inherited from Animal.speak()
Returns: "Buddy makes a sound"
my_dog.bark() called
Returns: "Buddy barks"
Expected Output
Parent attribute: Buddy
Child attribute: Golden Retriever
Animal speak method called
Dog bark method called
Basic Inheritance Benefits
Code Reusability - Dog inherits Animal methods
Single Inheritance - One parent class (Animal)
Simple and Easy to Understand
Method Override - Dog can override speak()
