To ensure all rows appear in a Python visual that groups automatically and hides duplicates, what should you do?

• A. Add a unique field to each row
• B. Disable grouping in the visual
• C. Remove duplicates by filtering
• D. Increase the visual size

Answer: (A)

Grouping in a Python visual can treat rows with the same values as a single item, which leads to duplicates being collapsed or hidden. By adding a unique field to each row, you give every record a distinct identity, so the visual’s grouping logic can’t merge them together. This ensures every original row appears, even when the data otherwise shares values across fields. Increasing the visual size won’t change the data, and disabling grouping or filtering duplicates would alter the data shown rather than preserve all rows.
