python学生管理系统的实现
本文实例为大家分享了python学生管理系统的具体代码,供大家参考,具体内容如下
```name_list = [] # 存储学生信息字典,学生信息用字典存,再用列表存储字典 # 菜单 def display_menu(): print("-"*30) print(" 学生管理系统 v8.8 ") print("1.添加学生信息") print("2.删除学生信息") print("3.修改学生信息") print("4.查询单个学生信息") print("5.查询所有学生信息") print("6.退出系统") print("-"*30) # 选择序号的获得 def get_choice(): selected_key = input("请输入选择的序号:") return selected_key # 检查性别是否合法 def check_sex(new_sex): flag = True while flag: if new_sex == '男' or new_sex == '女': flag = False else: new_sex = input("输入性别有误,请重新输入(男/女):") return new_sex # 检查电话号码是否合法 def check_phone(new_phone): flag = True while flag: if new_phone.isdigit(): flag = False else: new_phone = input("您输入的电话号码有误,请重新输入:") return new_phone # 检查学号是否重复或者有误 def check_id(new_id): flag = True while flag: # 先检查是不是纯数字再去考虑是否重复的事情,如果不是纯数字直接pass if new_id.isdigit(): for i in range(len(name_list)): if name_list[i]['id'] == new_id: new_id = check_id(input("您输入的学号重复,请重新输入:")) flag = False else: new_id = input("您输入的学号有误,请重新输入:") return new_id # 添加学生信息 def add_name(): new_info = {} new_id = check_id(input("请输入学号:")) new_info['id'] = new_id new_name = input("请输入姓名:") new_info['name'] = new_name new_sex = check_sex(input("请输入性别(男/女):")) new_info['sex'] = new_sex new_phone = check_phone(input("请输入电话号码:")) new_info['phone'] = new_phone name_list.append(new_info) print("添加成功!") # 查询所有学生信息 def find_all(): print("="*30) for name in name_list: print(name['id'], name['name'], name['sex'], name['phone']) print("=" * 30) # 删除学生信息 def del_name(): del_id_is = input("请输入要删除的学生学号:") flag = False index = 0 for i in range(len(name_list)): if name_list[i]['id'] == del_id_is: flag = True index = i break if flag: name_list.pop(index) print("删除成功!") else: print("学生未找到!请检查学号输入是否有误!") # 名字修改细节函数 def choice_of_name(index): while True: choice = input("请输入要修改学生的(1.id 2.姓名 3.性别 4.电话号码,5.全部修改):") if choice == '5': new_id = input("请输入新的学号:") name_list[index]['id'] = new_id new_name = input("请输入新的姓名:") name_list[index]['name'] = new_name new_sex = check_sex(input("请输入性别(男/女):")) name_list[index]['sex'] = new_sex new_phone = check_phone(input("请输入电话号码:")) name_list[index]['phone'] = new_phone break elif choice == '1': new_id = input("请输入新的学号:") name_list[index]['id'] = new_id break elif choice == '2': new_name = input("请输入新的姓名:") name_list[index]['name'] = new_name break elif choice == '3': new_sex = check_sex(input("请输入性别(男/女):")) name_list[index]['sex'] = new_sex break elif choice == '4': new_phone = check_phone(input("请输入电话号码:")) name_list[index]['phone'] = new_phone break else: print("输入有误,请重新输入!") # 修改学生信息 def re_name(): id_is = input("请输入要修改的学生学号:") flag = False index = 0 # 先找到要修改的学生的下标 for i in range(len(name_list)): if name_list[i]['id'] == id_is: flag = True index = i break if flag: choice_of_name(index) print("修改成功!") else: print("修改失败,学生信息未找到!") # 查询单个学生信息 def find_name(): find_id_is = input("请输入要查询的学生学号:") flag = False index = 0 for i in range(len(name_list)): if name_list[i]['id'] == find_id_is: flag = True index = i break if flag: print("学生查询到,学生信息为:") print(name_list[index]['id'], name_list[index]['name'], name_list[index]['sex'], name_list[index]['phone']) else: print("学生未找到!") def main(): exit_name = True while exit_name: display_menu() key = get_choice() if key == '1': add_name() elif key == '2': del_name() elif key == '3': re_name() elif key == '4': find_name() elif key == '5': find_all() elif key == '6': exit_name = False else: print("请输入正确的数值!") main()
