Python学生管理系统（录入、查找、删除、修改、排序、统计、显示学生信息）_DUANXU12的博客-CSDN博客_python显示学生信息 具体代码如下import osfilename='student.txt'def main(): while True: menm() choice=int(input('请选择')) if choice in [0,1,2,3,4,5,6,7]: if choice==0: answer=input('您确定要退出系统吗？y/n') if answer==' https://blog.csdn.net/DUANXU12/article/details/114678235

代码的框架结构如下，修改一下相关学生信息即可，参考代码：

def showStart():
    print('-' * 40)
    print('=' * 10 + '学生管理系统 v1.0' + '=' * 10)
    print('1.添加学生的信息')
    print('2.删除学生的信息')
    print('3.修改学生的信息')
    print('4.查询学生的信息')
    print('5.展示所有学生信息')
    print('6.退出系统')
    print('-' * 40)

    students.append(studentInformation)    
    return students

    modificationNum = input('请输入要修改学生的id：')
    x = -1
    for num in students:
        x += 1
        if modificationNum == num['id']:
            students[x] = addStudent()

def selectStudent(students):
    selectNum = input('请输入要查询学生的id：')
    judge = 1
    for student in students:
        if selectNum == student['id']:
            print('下面显示该学生的信息...')
            print('id  姓名  年龄\n')
            print(f"{student['id']}, {student['name']}, {student['age']}")
            judge = 0
            break
        if judge == 1:
            print('没有该学生...')

    print('下面显示班级所有学生信息...')
    print('id  姓名  年龄')

    del students[deleteNum]
    print('该学生信息已删除！')

    #     for r in readlines()[1:]:
    #         students.append({c:x for c,x in zip(col,r.split(','))})
    # print(students)
    students=[]
    while True:
        showStart()        
        key = int(input('请选择功能（序号）：'))
        if key == 1:
