Real examples, graded
WinPandas transformation 94/100
“The response is excellent, providing a highly accurate, idiomatic pandas solution with a well-designed smoke test and a clear, insightful explanation of the denominator. A very minor redundancy (using drop_duplicates before nunique) and the assumption of date-only inputs (without normalizing times via `.dt.normalize()`) keep it just shy of a perfect 10, but it is production-ready and expert-level.”
WeakMulti-file change plan 38/100
“The solution contains a logical bug in the SQL CASE statement regarding expiration and a timezone-naive datetime comparison issue in Python.”
