访问sqlite3数据库

       SQLite是一种轻型的嵌入式数据库，相对于其他的庞大的数据库，SQLite显得十分小巧。SQLite不需要安装，只需到http://www.sqlite.org下载一个Windows版的可执行文件即可。然后从命令行运行sqlite
sqlite3.exe python
新建一个python数据库，然后建表
sqlite>Create Table people(name varchar(30),age int,sex char(1));
输入数据
sqlite>insert into people values('Tom',20,'M');
sqlite>insert into people values('Jack',21,'M');
可用以下代码访问：

# -*- coding:utf-8 -*-
# file: PySqlite.py
#
import sqlite3                                            # 导入sqlite3模块
con = sqlite3.connect('python')                                    # 连接到数据库
cur = con.cursor()                                        # 获得数据库游标
cur.execute('insert into people (name,age,sex) values (\'Jee\',21,\'F\')')            # 执行SQL语句
r = cur.execute('delete from people where age=20')                        # 执行SQL语句
con.commit()                                            # 提交事务
cur.execute('select * from people')                                # 执行SQL语句
s = cur.fetchall()                                        # 获得数据
print s                                                # 打印数据
cur.close()                                            # 关闭游标
con.close()                                            # 关闭数据库连接
