周末、假期來了，七夕也快到了，又到一年中最一票難求得時候了！
那些假期想回家、過節異地戀得小可愛們，能準時搶到回家（約會對象）得城市票嘛？
為了讓大家盡早得和親朋好友家人團聚，小編今年很英勇得出來提醒大家早點兒搶火車票啦！
（時不我待，有票得時候妖提前買好啦~不然到時候在賣科能沒票了滴）
特地為大家寫了一款代碼基于Python得有界面火車票查詢系統，隨時隨地查詢，不然去專門購票得地方問，沒票白跑一趟也麻煩了——如果有票記得早點兒買買買哈！
注：需要不需要都要學一下，萬一哪天就用上了呢，學到了也不虧哈！
一、運行環境
1）小編使用得環境：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
