Neco 2020 Computer Studies Question 8

A teacher wants to keep a record of her class’s performance using a simple Python program. The program must read a text file named "scores.txt". Each line of the file contains a student’s name and their score (an integer between 0 and 100) separated by a comma, for example: John Doe,78 Jane Smith,85 ... The program should: 1. Compute the class average. 2. Identify the highest and lowest scores together with the corresponding student names. 3. Assign a grade to each student using the following scale: 70‑100 = A, 60‑69 = B, 50‑59 = C, 40‑49 = D, below 40 = F. 4. Write a new file "report.txt" that lists each student’s name, score, grade and, on the last line, the class average. Below is a draft of the program written by a student. It contains two logical errors. ```python with open('scores.txt', 'r') as f: lines = f.readlines() total = 0 count = 0 high = 0 low = 101 for line in lines: name, sc = line.split(',') score = int(sc) total += score count += 1 if score > high: high = score if score < low: low = score average = total / count with open('report.txt', 'w') as f: for line in lines: name, sc = line.split(',') score = int(sc) if score >= 70: grade = 'A' elif score >= 60: grade = 'B' elif score >= 50: grade = 'C' elif score >= 40: grade = 'D' else: grade = 'F' f.write(f"{name},{score},{grade}\n") f.write(f"Class Average: {average}\n") ``` Answer the following questions:
