使用Python實現火車票查詢系統(帶界面)
導語
周末、假期來瞭，七夕也快到瞭，又到一年中最一票難求的時候瞭！
那些假期想回傢、過節異地戀的小可愛們，能準時搶到回傢（約會對象）的城市票嘛？
為瞭讓大傢盡早的和親朋好友傢人團聚，小編今年很英勇的出來提醒大傢早點兒搶火車票啦！
（時不我待，有票的時候妖提前買好啦~不然到時候在賣科能沒票瞭滴）
特地為大傢寫瞭一款代碼基於Python的有界面火車票查詢系統，隨時隨地查詢，不然去專門購票的地方問，沒票白跑一趟也麻煩瞭——如果有票記得早點兒買買買哈！
註：需要不需要都要學一下，萬一哪天就用上瞭呢，學到瞭也不虧哈！
一、運行環境
1）小編使用的環境：Python3、Pycharm社區版、requests、PyQt5模塊、部分自帶就不一一展示啦。
模塊安裝：pip install -i https://pypi.douban.com/simple/+模塊名
二、代碼展示
1）爬取數據
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) # 匹配中文和對應的英文
stations = dict(stations) # 轉化成字典
# pprint(stations) # 以列的形式打印出來
2）主程序

三、效果展示
1）界面效果
2）時間日期
3）記錄刪除
