Question

Which practice avoids a common mistake with Descriptors?

  1. Ignore the Descriptors issue and rely on team discipline instead of clearer APIs or invariants.
  2. Silence the Descriptors problem by using broad catches, hidden globals, or extra shared mutable state.
  3. Prefer the version of Descriptors that makes behavior less predictable as long as the code still runs.
  4. Do not reach for custom descriptors as the default abstraction when a property or simpler class design already expresses the rule clearly.

Hint

Look for the option that protects correctness instead of hiding the problem.

Answer and rationale

Correct answer: D. Do not reach for custom descriptors as the default abstraction when a property or simpler class design already expresses the rule clearly.

Do not reach for custom descriptors as the default abstraction when a property or simpler class design already expresses the rule clearly. This is a common failure mode in real Python code and a frequent interview follow-up.
