[已解决]测试一下各个版本的准确率

rsj0315

下方是要求：
现在你是一个计算机开发者的角色，
现在要用python的第三方库streamlit写一个具有增删改查功能的通讯录管理系统，
数据库用的是sqlite，
侧边栏有增、删、改、查、退出几个radio按钮进行页面控制，
增加界面是一个form表单，有保存按钮，保存后自动清空form中的数据，并在下方用表格的形式显示数据库前10条数据；
查询界面是模糊查询，加按钮搜索的形式，同时有一个清空搜索框的按钮；
下方默认用表格的形式显示数据库前10条数据，每行数据后边有编辑和删除按钮；
当在查询界面选中某行数据时，可以点击进行编辑更新或者删除；
选择退出按钮，系统退出
上述代码输出后，需要各个功能按钮测试一下，不能有bug或者报错

这个问题的报错是因为在代码中没有连接到数据库。可以通过以下步骤修复这个问题：

1. 在代码的开头，添加连接到SQLite数据库的代码：

1. conn = sqlite3.connect('contacts.db')
   
2. c = conn.cursor()
   

复制代码

2. 在 create_table() 函数的开头，添加创建数据库表的代码：

1. c.execute('CREATE TABLE IF NOT EXISTS contact (name TEXT, email TEXT, phone TEXT, address TEXT)')
   

复制代码

3. 在 main() 函数的开头，添加连接到数据库的代码：

1. conn = sqlite3.connect('contacts.db')
   
2. c = conn.cursor()
   

复制代码

修复后的代码如下：

1. import streamlit as st

3. import pandas as pd
