How to use Python to implement a fully functional student management system.

Function Description

1. Divided into two interfaces: (1) Login and registration interface (2) Student management system interface
2. The login function is the same as the previously released library management system, login After success, you can enter the student management system interface, which will not be described here
3. System functions (1) Add student information (2) Delete student information (3) Modify student information (4) Query student information (5) Display all students Information (6) Exit
4. Many places have been optimized and improved, such as module import, login and registration, and carriage return without modification. The entire program code is about 200 lines.

Note: The code is divided into two modules and needs to be started in the student_main module. The student_main module is only responsible for input operations, while the student_tools module is responsible for specific student information system operation implementation functions. So everyone remember to create two .py files when copying the code.

The complete code is as follows

student_main module content code:

import student_tools

user=['wangtaotao']
pwd=['123456']

#登录
def denglu():
    users = input("请输入您的用户名:")
    pwds = input("请输入您的密码:")
    if users in user and pwds in pwd:
        student()
    else:
        print("账号或密码不正确，请重新输入")

#注册
def zhuce():
    users=input("请输入您要注册的用户名:")
    pwds=input("请输入您要注册的密码:")
    user.append(users)
    pwd.append(pwds)
    print()
    print("注册成功!")
    print()

#登录界面
def dljiemian():

    while True:
        print("---------------------------")
        print("    学生管理系统登陆界面 V1.0  ")
        print("                           ")
        print("        1:登   录           ")
        print("        2:注   册           ")
        print("        3:退   出           ")
        print("                           ")
        print("---------------------------")
        xx=input("请输入您的选择:")
        #1.登录
        if xx=='1':
            denglu()
        elif xx=='2':
        #2.注册
            zhuce()
        elif xx=='3':
        #3.退出
            print()
            print("成功退出!")
            print()
            break
        else:
            print("输入错误，请重新输入")

        if x=='1':
            student_tools.add()
        #删除学生
        elif x=='2':

        #修改学生
        elif x=='3':
            student_tools.xiugai()
        #查询学生
        elif x=='4':
            student_tools.find()
        #显示所有学生
        elif x=='5':
