使用Python实现火车票查询系统(带界面)
短信预约 -IT技能 免费直播动态提醒
导语
周末、假期来了，七夕也快到了，又到一年中最一票难求的时候了！
那些假期想回家、过节异地恋的小可爱们，能准时抢到回家（约会对象）的城市票嘛？
为了让大家尽早的和亲朋好友家人团聚，小编今年很英勇的出来提醒大家早点儿抢火车票啦！
（时不我待，有票的时候妖提前买好啦~不然到时候在卖科能没票了滴）
特地为大家写了一款代码基于Python的有界面火车票查询系统，随时随地查询，不然去专门购票的地方问，没票白跑一趟也麻烦了——如果有票记得早点儿买买买哈！
注：需要不需要都要学一下，万一哪天就用上了呢，学到了也不亏哈！
一、运行环境
1）小编使用的环境：Python3、Pycharm社区版、requests、PyQt5模块、部分自带就不一一展示啦。
模块安装：pip install -i https://pypi.douban.com/simple/+模块名
二、代码展示
1）爬取数据
import re
import urllib
from urllib import request
# from pprint import pprint
url = 'https://kyfw.12306.cn/otn/resources/js/framework/station_name.js?station_version=1.9048'
req = urllib.request.Request(url)
r = urllib.request.urlopen(req).read().decode('utf-8')
stations =re.findall(r'([\u4e00-\u9fa5]+)\|([A-Z]+)',r) # 匹配中文和对应的英文
stations = dict(stations) # 转化成字典
# pprint(stations) # 以列的形式打印出来
2）主程序
