# 1. 读取txt file3文件
with open('file3.txt', 'r') as file:
    lines = file.readlines()

# 2. 解析文本数据为学生对象或数据结构
students = []
for line in lines:
    name, score = line.strip().split(',')
    students.append({'name': name, 'score': int(score)})

# 3. 查找最高分数的学生姓名
highest_score = float('-inf')
highest_score_student_name = ''

for student in students:
    if student['score'] > highest_score:
        highest_score = student['score']
        highest_score_student_name = student['name']

print("Unix中分数最高的学生的姓名是：", highest_score_student_name)
