What is inheritance and how does it work in Python? Inheritance क्या है और Python में कैसे काम करता है?

class Animal:
    def __init__(self, name):
        self.name = name
    
    def speak(self):
        print(f'{self.name} makes sound')

class Dog(Animal):
    def speak(self):
        print(f'{self.name} barks: Woof!')

class Cat(Animal):
    def speak(self):
        print(f'{self.name} meows: Meow!')

# Creating objects
dog = Dog('Buddy')
cat = Cat('Whiskers')

dog.speak()  # Buddy barks: Woof!
cat.speak()  # Whiskers meows: Meow!

# Method Resolution Order (MRO)
print(Dog.__mro__)  # Shows inheritance chain

# super() to call parent methods
class Vehicle:
    def __init__(self, brand):
        self.brand = brand

class Car(Vehicle):
    def __init__(self, brand, model):
        super().__init__(brand)  # Call parent constructor
        self.model = model

car = Car('Toyota', 'Camry')
print(car.brand)  # Toyota
print(car.model)  # Camry
