python学生名片管理vv2.0是在1.0的基础上增加部分功能，实现将数据存入文件保存，以便于程序停止后还能再次取到数据。具体实现请看如下部分：

card_main.py

import sys
from One.card_func2 import *

def head():
 print('*' * 30)
 print('学生信息管理系统v2.0')
 print('1.添加学生\t2.显示所有\t3.查询学生\t0.退出系统')
 print('*' * 30)


def main():
 while True:
 head()
 num = input('输入操作:')
 if num == '1':
  print('选择功能添加学生')
  add_card()
 elif num == '2':
  print('选择功能添显示所有')
  show_all()
 elif num == '3':
  print('选择功能查询学生')
  search_card()
 elif num == '0':
  sys.exit()
 else:
  print('输入有误,命令无效')
