Question

What deeper point about __slots__ should a senior Python developer mention?

  1. Senior answers mention tradeoffs, not just memory savings, because __slots__ changes flexibility and interoperability.
  2. At senior level, the right answer is that __slots__ exists mostly for historical syntax reasons.
  3. At senior level, Python removes the tradeoffs around __slots__, so design choices barely matter in practice.
  4. At senior level, any approach to __slots__ 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: A. Senior answers mention tradeoffs, not just memory savings, because __slots__ changes flexibility and interoperability.

Senior answers mention tradeoffs, not just memory savings, because __slots__ changes flexibility and interoperability. This is the kind of tradeoff-aware answer senior interviews usually expect.
