Python Student Information Management System Tutorial with Complete Source Code

The tutorial introduces a simple student information management system implemented in Python, outlining six core functionalities: add, delete, modify, search, display all student records, and exit the program.

System Overview

The system repeatedly shows a menu, accepts a numeric choice from the user, and calls the corresponding function until the user selects the exit option.

Key Functions

def info_print(): print('--------请选择功能-----') print('1、添加学生') print('2、删除学生') print('3、修改学生') print('4、查询学生') print('5、显示所有学生') print('6、退出系统') print('-' * 20)

def add_info(): """添加学生函数""" new_id = input('输入学号：') new_name = input('输入姓名：') new_tel = input('输入手机号：') global info for i in info: if new_name == i['name']: print('此用户已经存在，请勿重复添加') return info_dict = {'id': new_id, 'name': new_name, 'tel': new_tel} info.append(info_dict) print(info)

def del_info(): """删除学生""" del_name = input('请输入要删除的学生的姓名：') global info for i in info: if del_name == i['name']: info.remove(i) break else: print('该学生不存在！') print(info)

def modify_info(): """修改函数""" modify_name = input('请输入要修改的学生的姓名：') global info for i in info: if modify_name == i['name']: i['tel'] = input('请输入新的手机号：') break else: print('该学生不存在') print(info)

def search_info(): """查询学生信息""" search_name = input('请输入要查找的学生姓名：') global info for i in info: if search_name == i['name']: print('找到该学生的信息如下：') print(f"该学生的学号是{i['id']},姓名是{i['name']},手机号是{i['tel']}") break else: print('该学生不存在！')

def print_all(): """显示所有学生信息""" print('学号\t姓名\t手机号') for i in info: print(f"{i['id']}\t{i['name']}\t{i['tel']}")

The main loop ties everything together:

while True: info_print() user_num = eval(input('请输入功能序号：')) if user_num == 1: add_info() elif user_num == 2: del_info() elif user_num == 3: modify_info() elif user_num == 4: search_info() elif user_num == 5: print_all() elif user_num == 6: exit_flag = input('确定要退出吗？yes/no?') if exit_flag == 'yes': break else: print('输入的功能序号有误！')
