在win10上利用Python3.6制作火车票余票查询小程序

import re
import requests
from pprint import pprint 

url = 'https://kyfw.12306.cn/otn/resources/js/framework/station_name.js?station_version=1.8971'
response = requests.get(url, verify=False)
stations = re.findall(u'([\u4e00-\u9fa5]+)\|([A-Z]+)', response.text)
pprint(dict(stations), indent=4)

将上面代码运行产生的输出保存为stations.py,并将字典赋给变量stations

用pip安装没有的模块，具体的一些程序的作用可以参考实验楼中关于火车票余票查询的课程

效果如下图所示：
