Problem
fix#62998
When using
DataFrame.query()to filter string columns based on list membership, aTypeErroroccurs due to multiline string representation of dtypes in internal methods.Reproducible Example:
Previously raised: TypeError: dtype ' object\n object\ndtype: object' not understood
result = df.query(f"Country in {un}")
Solution
Modified _get_cleaned_column_resolvers in pandas/core/generic.py to detect and handle the specific case of multiline dtype string representations before creating Series objects.
