What is inheritance in Python?
PICTURE THIS: OOP PILLARS
Simple meaning
Inheritance lets a subclass reuse and extend a parent class's attributes and methods.
WHY — OOP instead of guessing?
Why interviewers care about OOP:
who only read docs from people who shipped.
and tied to Python work.
Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1Inheritance lets a subclass
reuse and extend a parent class's attributes and methods.
- 2Python supports single and
multiple inheritance, resolving names through the method resolution order.
- 3It is useful for
sharing behavior, but composition is often clearer when types are not a true is-a relationship.
- 4Give an example
One tiny concrete case you can say aloud.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.

Key takeaway
Inheritance lets a subclass reuse and extend a parent class's attributes and methods. Python supports single and multiple inheritance, resolving names through the method resolution order.
