我的第一个python程序

人生苦短，我用python！

最近几天看了一下简明python教程，然后最后写了一个python查询、修改、删除、显示人名称和地址的小程序。菜鸟刚刚入门，啥也不会。

我为什么要学习python？我这个人就是有这个毛病，啥都想知道，但是啥都学不精通。唉，啥时候能踏踏实实好好的做好一件事情呢。这是我的第一个python程序，虽然菜，但还是贴出来做个纪念吧~这个程序让我对列表、字典都有了更进一步的了解。下一步就是看下python界面编程吧，然后学好了以后写一个简单的python贪吃蛇吧。这个学习也要继续进行下去。

好久没搞驱动了，还得再看看。师兄马上就毕业了，我得加紧跟师兄多沟通沟通。模型仿真控制这边也要弄。时不我待，再不学习就老了！
