Multiple choiceEasychapter-8-curatedpremiumpythonic-data-processinglist-comprehensions
Answer and explanation
Correct answer
B. Use a comprehension when the mapping or filtering rule is compact enough that the reader can hold it comfortably in one pass.
Why
Use a comprehension when the mapping or filtering rule is compact enough that the reader can hold it comfortably in one pass. That is the stronger engineering move because interviewers often ask when you would choose a loop instead, because judgment matters more than syntax knowledge. If the comprehension becomes a maze of conditions and nested logic, the code stops being a clarity win.
