Question

What deeper point about Lists as Dynamic Arrays should a senior Python developer mention?

  1. At senior level, the right answer is that Lists as Dynamic Arrays exists mostly for historical syntax reasons.
  2. Senior answers mention dynamic-array over-allocation, amortized append cost, and why locality helps practical performance.
  3. At senior level, Python removes the tradeoffs around Lists as Dynamic Arrays, so design choices barely matter in practice.
  4. At senior level, any approach to Lists as Dynamic Arrays is equally correct if it passes one small local test.

Hint

Look beyond syntax and explain the runtime, API, or design consequence.

Answer and rationale

Correct answer: B. Senior answers mention dynamic-array over-allocation, amortized append cost, and why locality helps practical performance.

Senior answers mention dynamic-array over-allocation, amortized append cost, and why locality helps practical performance. This is the kind of tradeoff-aware answer senior interviews usually expect.
