Inheritance vs Polymorphism | Dataford Interview Questions

What is the difference between inheritance and polymorphism?

Implement a Python function that demonstrates both concepts by formatting notification records through a shared interface. Each record must be converted to the appropriate subclass, and the function must invoke the same polymorphic method for every object.

Input: a list of dictionaries with type and type-specific fields. Output: a list of formatted strings in the original order.

Supported formats: email produces EMAIL: recipient | subject, SMS produces SMS: phone | body, and push produces PUSH: device | title: body.

Constraints

0 <= len(records) <= 100
Each record type is one of email, sms, or push
Records contain all fields required by their type
Return results in the same order as the input

Function Signature

def format_notifications(records):
