import json
import random
class Province:

        headers = {"Content-Type": "application/x-www-form-urlencoded"}
        rep = requests.get(url=url,headers=headers)
        str_list = re.findall('<string>(.+?)</string>',rep.text)

        return (str_list)

    def get_city(self):

        根据省份获取城市响应

        url = "http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity"
        province_random = random.choice(self.get_province())
