Refactor a Data Processing Script | Dataford Interview Questions

There was a question with some python code that processed data and I was asked to refactor it.

Refactor the data-processing logic without changing its intended behavior: combine records with the same id by summing their amount values, and return results in the order each ID first appears. Implement def refactor_records(records):.

Input is a list of dictionaries containing a string id and integer amount. Return a list of dictionaries containing id and total.

Constraints

0 <= len(records) <= 1000
Each record contains a non-empty string id
Each amount is an integer
The output preserves the first-seen order of distinct IDs

Function Signature

def refactor_records(records):
