标签：des style blog http color 使用 os 文件

近期一直在学习python和批处理，来将工作中的手工操作的低效环节用脚本自动实现。

已经实现了几个脚本。但是命令行窗口，总是不太友好，对执行结果的反馈也不清楚，就想实现可视化。

在网上找到Python可视化的编程的一个方法，周末专心实现了一下，效果还行，算是有头绪了。

主要是按照上面这篇博客的方法实现的。感谢作者。

一、环境与软件版本

Eric特别挑软件版本，与PyQt 和 python的版本都要对应。

在网上搜索，以及自己安装尝试，验证Win7 64可用的软件版本配合为：

[Python3.3.2] + [PyQt4-4.10.2-gpl-Py3.3-Qt4.8.4-x64] + [Eric5.4.5]

二、实现的效果

输入路径，点击“文件列表”，会在文本框中显示文件列表。这是为下一步进行文件处理打基础。

点击“清空”，清空路径与文本框。

点击“退出”，关闭程序。
