用python进行IP地址查询

最近在学python，利用淘宝的RestApi：http://ip.taobao.com/instructions.php;写了个ip地址查询工具

import requests
import json
import re

def real_address(ip):
    '''
    Return your real address  in json
    Using ip.taobao.com api
    '''
    url = 'http://ip.taobao.com/service/getIpInfo.php?ip=%s' % ip
    response = requests.get(url)
    return json.loads(response.content)

# 查询本机的外网ip
def my_ip():
    '''Return your own ip address'''

    data = requests.get('http://www.whereismyip.com')
    return re.search('d+.d+.d+.d+',data.content).group(0)

def print_json(data):
    keys = ['ip', 'country', 'region', 'city', 'isp']
    for key in keys:
        print data['data'][key],

if __name__ == '__main__':
    print_json(real_address(my_ip()))
