Interview Question

What is inheritance?

Inheritance lets subclasses reuse and specialize base-class behavior.

💡 Concept ✅ Quick Revision 🐍 Python

Answer

Inheritance lets a class derive attribute behavior from base classes. • A subclass lists its bases in the class definition. • Method resolution order controls attribute lookup across bases. • Composition may be clearer when the relationship is not truly “is-a.”

💡 Simple Example

class Animal:
    def speak(self):
        return 'sound'

class Dog(Animal):
    pass

print(Dog().speak())

Output

sound
