Question

有一学科各科成绩数据（数据格式：姓名，语文，数学），读取上述文件数据，并计算语文数学的平均分，筛选出语文成绩大于35分的学生姓名

Answer 1

没看到你说明文件格式，我这里是.txt 文件格式：代码如下：

# 定义一个学生类
class Student:
    def __init__(self, name, chinese, math):
        self.name = name
        self.chinese = chinese
        self.math = math

    def get_average(self):
        # 计算平均分
        return (self.chinese + self.math) / 2

# 读取文件数据
with open("score.txt", "r", encoding="utf-8") as f:
    lines = f.readlines()

# 存储学生数据
students = []
for line in lines:
    name, chinese, math = line.strip().split(",")
    student = Student(name, int(chinese), int(math))
    students.append(student)

# 计算语文数学平均分
chinese_total = 0
math_total = 0
for student in students:
    chinese_total += student.chinese
    math_total += student.math
chinese_average = chinese_total / len(students)
math_average = math_total / len(students)
print("语文平均分：", chinese_average)
print("数学平均分：", math_average)

# 筛选语文成绩大于35分的学生姓名
names = []
for student in students:
    if student.chinese > 35:
        names.append(student.name)

# 输出到文件
with open("result.txt", "w", encoding="utf-8") as f:
    for name in names:
        f.write(name + "\n")
