由于python的数据库模块有专门的数据库模块的规范，所以，其实不管使用哪种数据库的方法都大同小异的，这里就给出一段示范的代码：
#-*- encoding: gb2312 -*-
import os, sys, string
import MySQLdb
# 连接数据库
try:
conn = MySQLdb.connect(host='localhost',user='root',passwd='xxxx',db='test1')
except Exception, e:
print e
sys.exit()
# 获取cursor对象来进行操作
cursor = conn.cursor()
# 创建表
sql = "create table if not exists test1(name varchar(128) primary key, age int(4))"
cursor.execute(sql)
# 插入数据
sql = "insert into test1(name, age) values ('%s', %d)" % ("zhaowei", 23)
try:
cursor.execute(sql)
except Exception, e:
print e
sql = "insert into test1(name, age) values ('%s', %d)" % ("张三", 21)
try:
cursor.execute(sql)
except Exception, e:
print e
# 插入多条
sql = "insert into test1(name, age) values (%s, %s)"
val = (("李四", 24), ("王五", 25), ("洪六", 26))
try:
cursor.executemany(sql, val)
except Exception, e:
print e
#查询出数据
sql = "select * from test1"
cursor.execute(sql)
alldata = cursor.fetchall()
# 如果有数据返回，就循环输出, alldata是有个二维的列表
if alldata:
for rec in alldata:
print rec[0], rec[1]
cursor.close()
conn.close()
