数据处理过程中，研究者常会遇到收集的数据与预期采用的工具不匹配问题。目前，常用的方式是 Datatransfer 等数据格式转换器，通过导入及导出实现数据格式的转换，缺点是软件收费以及当代转换的数据多时，耗时耗力。鉴于此，本文借助于 python 以及 python 与 Stata 相结合的方法提出两种可实现批量数据格式快速转换的方案。
In the process of data processing, researchers often encounter the mismatch between the collected data and the expected tools. At present, the commonly used method is data format converter such as data transfer. The data format conversion is realized by importing and exporting. The disadvantage is that the software charges and the data converted at present are time-consuming and labor-consuming. In view of this, with the help of Python and the combination of Python and Stata, this paper puts forward two schemes that can realize the fast conversion of batch data format.

困扰：你的电脑里下载了许多日本av，而且这av在某个目录树下，很多子目录，一共有上万个av文件，
可是又不想被小孩或其它播放器搜索到不小心打开播放，
于是你有了个简单易用的想法：
当自己不想看这些电影时，把这数万个av的扩展名，改成其它，比如改成图片的扩展名.jpeg
当自己想看这些电影时，把这数万个av的扩展名，恢复成原样
可是要自己手动一个个修改，实在费神费力，
如果手动全选后再修改，又会把原有文件名改的乱七八杂，况且很多文件格式并不是都相同！
于是你有了个更好更快捷的想法，快速方便的批量改扩展名和恢复的原名
于是本人帮你设计了个C的DOS界面程序，
设计目的：方便自己方便他人

你有没有打开过你计算机的机箱呢？你会发现你的机器由很多部件组成。视频卡产生图形，发射数字信号到
处理者。声卡把声音信号混合后送到扬声器。同样，键盘、鼠标等其他这些输入设备，是游戏必要的使用设备。在家用电脑的出现的早期，程序员必须了解计算机的
每个元件。游戏程序员必须阅读每个计算机设备的技术文档，并编写驱动程序来通信。这种情形变得越来越坏，当不同的计算机厂商生产出不同的设备时。由于兼容

样，编写游戏同样还是挺困难的。但是幸运的是，Pygame的出现使我们没必要担心细节。
