Multiple choiceMediumchapter-1-curatedpremiumpython-fundamentalstracing-and-code-reading
Answer and explanation
Correct answer
B. Make the rule clearer and easier to explain. Trace one real example line by line and predict intermediate values before you start changing the code.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Jumping straight into edits without understanding the current behavior often turns one bug into two.
