Question
When should a Python developer choose Sorting, Key Functions, and Timsort deliberately?
- Choose Sorting, Key Functions, and Timsort mainly when you want to postpone validation and fix issues manually later.
- Use key functions when sorting objects or rows by one or more derived business fields.
- Choose Sorting, Key Functions, and Timsort whenever you want the code to look more advanced, even if the design gets less clear.
- Choose Sorting, Key Functions, and Timsort 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: B. Use key functions when sorting objects or rows by one or more derived business fields.
Use key functions when sorting objects or rows by one or more derived business fields. Interviewers often ask this to see whether you can connect the concept to real design decisions.
