python 模仿web页面检测域名是否被注册

最近在给朋友弄个网站，网站基本弄好以后就要申请个域名，以前也接触过域名注册的，这次想真个拉风点的域名，结果。。。令人大失所望。
在不断重复的提交后，发现可以弄个程序检测一下有没有好点的域名，这样就不用人为输入域名了。然后就有了 下面的代码。

#!/bin/env python
#coding=gbk
import urllib
import urllib2
import time

'''关键字构造'''
def analysis(radix,keyword,lenSize):
    global res_f
    global res_e
    if radix==10:
        if keyword<radix:
            res_f.append(keyword)
        else:
            res_f.append(keyword%radix)
            analysis(radix,keyword/radix,lenSize)
    else:
        if keyword<radix:
            res_e.append(keyword)
        else:
            res_e.append(keyword%radix)
            analysis(radix,keyword/radix,lenSize)
