创建一个包含学生的文件，并查看从5开始具有更多平均成绩的学生的信息以及每个学生的平均成绩

# 读取学生信息文件
file = open("students.txt", "r")
lines = file.readlines()
file.close()

# 存储学生信息的列表
students = []

# 解析学生信息并计算平均成绩
for line in lines:
    data = line.strip().split(",")
    name = data[0]
    student_id = data[1]
    grade = int(data[2])
    subject_scores = list(map(int, data[3:]))

    # 计算平均成绩
    average_score = sum(subject_scores) / len(subject_scores)

    # 存储学生信息
    student = {
        "name": name,
        "student_id": student_id,
        "average_score": average_score
    }
    students.append(student)

# 查找平均成绩大于等于5的学生信息
selected_students = [student for student in students if student["average_score"] >= 5]

# 打印符合条件的学生信息和平均成绩
for student in selected_students:
    print("姓名:", student["name"])
    print("学号:", student["student_id"])
    print("平均成绩:", student["average_score"])
    print("---")
