如何使用Python实现全功能的学生管理系统？

功能描述

1.分为两个界面：（1）登录和注册界面 （2）学生管理系统界面
2.登录功能和之前发布的图书管理系统相同，登录成功后可进入学生管理系统界面，这里不再叙述
3.系统功能（1）添加学生信息（2）删除学生信息（3）修改学生信息（4）查询学生信息（5）显示所有学生信息（6）退出
4.有很多地方增加了优化，也进行了完善，如模块导入、登录注册以及回车不修改等功能。整个程序代码大概200行。

注意：代码分为两个模块，需要在student_main模块中启动。student_main模块中只负责输入操作，而student_tools模块中负责具体的学生信息系统操作实现功能。所以大家在拷贝代码的时候记得创建两个.py文件。

完整代码如下

student_main模块内容代码:

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")
#学生管理系统
def student():
    while True:
        #调用student_tools模块中的界面函数
        student_tools.jiemian()
        x=input("请输入您的选择:")
        #添加学生
        if x=='1':
            student_tools.add()
        #删除学生
        elif x=='2':
            student_tools.dele()
        #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':
            student_tools.showall()
        #退出学生管理系统,返回上一层登录界面系统
        elif x=='6':
            print()
            print("成功退出学生管理系统!")
            break
        else:
            print()
            print("输入错误，请重新输入")
            print()

#调用最先执行的登录界面函数
dljiemian()
