Multiple choiceEasychapter-8-curatedpremiumpythonic-data-processinglist-comprehensions
Answer and explanation
Correct answer
D. When the rule is no longer easy to trace, explain, or change without breaking nearby behavior.
Why
A refactor is justified when the code stops communicating its intent. Use a comprehension when the mapping or filtering rule is compact enough that the reader can hold it comfortably in one pass.
