Question

Which practice avoids a common mistake with Decorators?

  1. Ignore the Decorators issue and rely on team discipline instead of clearer APIs or invariants.
  2. Silence the Decorators problem by using broad catches, hidden globals, or extra shared mutable state.
  3. Prefer the version of Decorators that makes behavior less predictable as long as the code still runs.
  4. Do not use decorators to hide important business logic or complex control flow that callers still need to reason about directly.

Hint

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

Answer and rationale

Correct answer: D. Do not use decorators to hide important business logic or complex control flow that callers still need to reason about directly.

Do not use decorators to hide important business logic or complex control flow that callers still need to reason about directly. This is a common failure mode in real Python code and a frequent interview follow-up.
