Domain Modeling · interview question
A teammate submits shaky invariants in __post_init__ code. Which review comment is the strongest?
Multiple choiceMediumchapter-7-curatedpremiumdomain-modelinginvariants-in-post-init
Answer and explanation
Correct answer
C. Make the rule clearer and easier to explain. Enforce the basic invariant when the object is created so the rest of the code can trust the instance.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Letting invalid objects exist and hoping later code cleans them up makes bugs harder to localize.
