Object-Oriented Programming

Classes bundle data and behavior.

class Animal:
    def speak(self):
        return "?"

class Dog(Animal):
    def speak(self):
        return "Woof"

pet = Dog()
print(pet.speak())

C# uses similar syntax with explicit access modifiers, while JavaScript prototypes underpin its classes.

Practice Questions

   Answer

2. Which C# syntax is analogous to Python’s class Dog(Animal) inheritance?
