Python下MySQLdb库的项目地址是：http://sourceforge.net/projects/mysql-python/
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)
conn.commit()
print n
注：executemany 的param可以传入一个序列，批量执行
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")
n = cursor.execute(sql,param)
print n
关闭：
cursor.close() conn.close()
