web_url = "www.ip138.com"    
u1 = "/ips8.asp?ip="
u2 = "112.254.67.142"
u3 = "&action=2"
#getUrl = u1 + u2 + u3

fd = open('1.txt','r+')
for line in fd.readlines():
    #rstrip去掉右边空格和回车换行符
    getUrl = u1 + line.rstrip() + u3
       
    conn = httplib.HTTPConnection(web_url)
    conn.request("GET", getUrl)
    r1 = conn.getresponse()
    data1 = r1.read()
    #都是将gb2312编码的str转为unicode编码
    #print data1.decode('gb2312')
    #keyword = re.compile(r'''<td align="center"><ul class="ul1"><li>(.*?)</li></ul></td>''', re.U|re.S)
    keyword = re.compile(r'''<td align="center"><ul class="ul1"><li>(.*?)</li><li>''', re.U|re.S)
    a = re.findall(keyword,data1)
    print line.strip() + "\t" + a[0].decode('gb2312')
    conn.close()
   
fd.close()

1.txt 内容如下：

119.128.200.90
218.90.169.90
219.129.242.180
183.69.189.172
222.89.193.18
221.193.222.105
59.151.213.135
218.22.182.50
124.238.192.23
113.111.94.116
115.182.53.30

执行上面的程序就会显示ip的地理位置。需要python环境支持。
