  AI Trap of the Week · Review & hallucination · spotter

The plausible-looking pandas import

An AI assistant wrote this ETL helper. It imports cleanly in the assistant's preview, but you haven't run it yet.

import pandas as pd
from pandas.helpers import dedupe_keys

def dedupe(df: pd.DataFrame, keys: list[str]) -> pd.DataFrame:
    keys = dedupe_keys(keys)
    return df.drop_duplicates(subset=keys, keep="last")

Should you merge this?
