Coding: Python OOP Concepts | Dataford Interview Questions

Explain Python OOP concepts: init, dunder methods, abstraction, and inheritance

Asked in the Skill/Technical Round stage. Python fundamentals.

Implement an abstract Shape base class and Rectangle and Circle subclasses. Use __init__ for initialization, abstract methods for area() and perimeter(), and dunder methods for readable string output and equality. Implement shape_summary(specs), where each specification is a dictionary with type and args, and return one summary dictionary per shape.

Input and Output

specs is a list of dictionaries. Return dictionaries containing text, rounded area, rounded perimeter, and same_as_previous.

Constraints

Each shape type is rectangle or circle.
Rectangle arguments contain exactly two positive numbers.
Circle arguments contain exactly one positive number.
Return numeric results rounded to two decimal places.

Function Signature
