Question

In Python, which comparison about Dictionaries and Hash Tables is accurate?

  1. Dicts are optimized for named-key access, while lists require linear scans unless the position itself is the key.
  2. There is no practical difference in behavior, performance, or maintainability when Dictionaries and Hash Tables is involved.
  3. The oldest option related to Dictionaries and Hash Tables is always the right production choice regardless of workload or context.
  4. Differences around Dictionaries and Hash Tables are mostly cosmetic, so correctness and debugging quality do not really change.

Hint

Focus on the behavior or tradeoff, not just the keyword.

Answer and rationale

Correct answer: A. Dicts are optimized for named-key access, while lists require linear scans unless the position itself is the key.

Dicts are optimized for named-key access, while lists require linear scans unless the position itself is the key. This is the comparison that usually separates memorization from understanding.
