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？

 所有文章完整的素材+源码都在

粉丝白嫖源码福利，请移步至CSDN社区或文末公众hao即可免费。

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！
