7. 列出所有学生信息功能的实现

实现方法

• 班级相关模块：class_room.py

import student
from student import Student
import tools


class ClassRoom:
    '''班级类型'''
    def __init__(self, class_name):
        self.class_name = class_name  # 班级名称
        self.student = []  # 保存学生信息

...

    def list_all_student_info(self, student_list):
        '''显示所有学生的信息'''
        print('+------+----------------------+--------+--------+')
        print('| 序号 |         姓名         |语文成绩|数学成绩|')
        print('+------+----------------------+--------+--------+')
        number = 1
        for stu in student_list:
            print('| %4d | %s |  %4d  |  %4d  |' % (
                number, tools.center_to_display_width(stu.name, 20),
            stu.chinese_score, stu.math_score))
            number += 1
        if len(student_list):
            print('+------+----------------------+--------+--------+')
...

    def student_manager(self):
        '''此函数用来学生数据'''
        while True:
            self.show_class_menu()
            sel = input('请选择：')
            match sel:
                case '1':  # 1) 添加学生
                    self.add_student()
                case '2':  # 2) 修改学生的语文成绩
                    pass
                case '3':  # 3) 修改学生的数学成绩
                    pass
                case '4':  # 4) 删除学生
                    pass
                case '5':  # 5) 列出所有学生的成绩
                    self.list_all_student_info(self.student)
                case '6':  # 6) 按语文成绩从高到低显示学生成绩
