MySQLdb是Python 连接 MySQL 的模块，下面是它一些简单的使用方法：

# -*- coding: utf-8 -*-     
#mysqldb    
import time, MySQLdb    
  
#连接    
conn=MySQLdb.connect(host="localhost",user="root",passwd="",db="test",charset="utf8")  
cursor = conn.cursor()    
   
#写入    
sql = "insert into user(name,created) values(%s,%s)"   
param = ("aaa",int(time.time()))    
n = cursor.execute(sql,param)    
print n    
   
#更新    
sql = "update user set name=%s where id=3"   
param = ("bbb")    
n = cursor.execute(sql,param)    
print n    
   
#查询    
n = cursor.execute("select * from user")    
for row in cursor.fetchall():    
    for r in row:    
        print r    
   
#删除    
sql = "delete from user where name=%s"   
param =("aaa")
