python爬虫学习之查询IP地址对应的归属地

import requests

def getIpAddr(url):
    response = requests.get(url)
    response.encoding=response.apparent_encoding
    content = response.text
    #print(len("四川省成都市 电信"))  python 汉字算一个字节
    #print(type(content))
    str = content[content.find("WhwtdWrap bor-b1s col-gray03"):content.find("clearfix plr10")-87] # 大致筛选出归属地所在的字符串
    a = str[::-1]
    b = a[0:a.find(">")]
    return b[::-1]

if __name__ == '__main__':
    url = "http://ip.tool.chinaz.com/"
    ipAdd = input("请输入IP地址：")
    url = url + ipAdd
    str = getIpAddr(url)
    print("IP的归属地为：："+str)
