Question
When should a Python developer choose Type Hints and mypy deliberately?
- Add type hints where they clarify inputs, outputs, and shaped data so changes can be made with more confidence.
- Choose Type Hints and mypy mainly when you want to postpone validation and fix issues manually later.
- Choose Type Hints and mypy whenever you want the code to look more advanced, even if the design gets less clear.
- Choose Type Hints and mypy 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: A. Add type hints where they clarify inputs, outputs, and shaped data so changes can be made with more confidence.
Add type hints where they clarify inputs, outputs, and shaped data so changes can be made with more confidence. Interviewers often ask this to see whether you can connect the concept to real design decisions.
