Question
When should a Python developer choose Sets and Membership Testing deliberately?
- Choose Sets and Membership Testing mainly when you want to postpone validation and fix issues manually later.
- Choose Sets and Membership Testing whenever you want the code to look more advanced, even if the design gets less clear.
- Use a set for de-duplication, seen-tracking, or fast contains checks inside parsing and traversal code.
- Choose Sets and Membership Testing only to avoid modeling the real data shape or domain contract explicitly.
Hint
Think about the production scenario where the choice genuinely improves the code.
Answer and rationale
Correct answer: C. Use a set for de-duplication, seen-tracking, or fast contains checks inside parsing and traversal code.
Use a set for de-duplication, seen-tracking, or fast contains checks inside parsing and traversal code. Interviewers often ask this to see whether you can connect the concept to real design decisions.
