学生成绩录入浏览代码

学生成绩录入和浏览通常涉及到数据库操作和用户界面交互的编程。以下是一个简单的伪代码示例，展示了如何设计这样的功能：

# 定义学生类
class Student:
    def __init__(self, id, name, scores):
        self.id = id
        self.name = name
        self.scores = scores

# 数据库操作
def enter_score(student_id, course, score):
    # 连接到数据库
    db_connection = connect_to_database()
    
    # 插入成绩记录
    insert_into_scores_table(db_connection, student_id, course, score)
    db_connection.close()

def view_scores(student_id):
    # 连接到数据库
    db_connection = connect_to_database()
    
    # 查询学生的成绩
    scores_data = fetch_scores_by_student_id(db_connection, student_id)
    print("学生{}的成绩：".format(student_id))
    for course, score in scores_data.items():
        print(f"{course}: {score}")
    
    db_connection.close()

# 用户界面
def main():
    while True:
        action = input("请输入操作（录入分数/查看分数/退出）：")
        
        if action == "录入":
            student_id = int(input("输入学生ID："))
            course = input("输入课程名：")
            score = float(input("输入分数："))
            enter_score(student_id, course, score)
        elif action == "查看":
            student_id = int(input("输入学生ID："))
            view_scores(student_id)
        elif action == "退出":
            break
        else:
            print("无效操作，请重试.")

if __name__ == "__main__":
    main()
