Format the Conference Badge Label

PandasEasyJunior level~10 min

Problem

You are given a DataFrame `attendee` with columns `attendee_id`, `full_name`, and `department`.

Build a badge label for every attendee: the attendee's full name followed by the first letter of their `department` in parentheses, for example 'Harper(M)' for someone in Marketing. The case of that first letter is kept as-is.

Return two columns, `attendee_id` and `label`, ordered by `attendee_id` from highest to lowest.

Input data

Example rows — the live problem includes the full dataset.

attendee

attendee_id	full_name	department
1	Harper	Sales
3	Quinn	Analytics
2	Reyes	Product
4	Soto	Design
6	Vance	Engineering

Expected output

Your answer should return 6 rows with the columns attendee_id, label.
