python cgi编程与mysql/ target=_blank class=infotextkey>mysql数据库操作：
1、把数据库服务器的信息录入到表内。
2、利用python的cgi脚本从表中按照规则读取数据。
3、用web界面展示。
第一步，创建数据表(字段解释参照cgi部分):
第二步，python实现web cgi脚本
#!/usr/bin/python
#coding=utf-8
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
#这两个的作用是设置python默认编码为utf8
import MySQLdb
import cgi
print "Content-Type: text/html charset=utf-8 n"
print "<html><head><title>数据库列表</title></head>"
print "<body>"
print "<h1>数据库列表</h1>"
print "<ul>"
print '''
