Multiple choiceHardchapter-8-curatedpremiumiterators-and-generatorsiterator-protocol
Answer and explanation
Correct answer
B. Make the rule clearer and easier to explain. Know that iterables hand out iterators and that iterators produce one value at a time until exhaustion.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Treating iteration as magic makes advanced debugging and custom data-flow design much harder.
