Case Study: A teacher wants a simple Python script to analyze daily attendance from a CSV file named 'attendance.csv'. Each row has two columns: 'roll_no' and 'status' ('P' for present, 'A' for absent). The script counts how many times each student is present and flags students below 75% attendance. Question: To map each student's unique roll number to their corresponding present count, which Python data structure is most suitable?
