Question
When should a Python developer choose Dictionaries and Hash Tables deliberately?
- Choose Dictionaries and Hash Tables mainly when you want to postpone validation and fix issues manually later.
- Choose a dict when the main question is 'find the value for this key' rather than 'scan every item in order'.
- Choose Dictionaries and Hash Tables whenever you want the code to look more advanced, even if the design gets less clear.
- Choose Dictionaries and Hash Tables 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. Choose a dict when the main question is 'find the value for this key' rather than 'scan every item in order'.
Choose a dict when the main question is 'find the value for this key' rather than 'scan every item in order'. Interviewers often ask this to see whether you can connect the concept to real design decisions.
