【Python】Python PYQT4 GUI编程与exe打包

　　本篇文章承接http://www.cnblogs.com/zhang-zhi/p/7646923.html#3807385，上篇文章描述了对文本文件的简单处理，本章节结合PYQT4实现该功能的GUI图形界面化，简单的UI界面可以更好的提高工具的实用性，所以在此进行一下记录。

主要实现功能效果展示如下：

1、打开本地对话框，选择文件

2、文件打开，报文输入及报文清空功能

3、核心功能，报文格式转换

4、退出

一、Python GUI开发之PYQT4

1、先安装PYQT4

有两种方式可以下载：

①pip下载，终端运行pip install pyqt4

②pycharm工具安装

打开pycharm工具，点击“File”→“settings”→“Project：Project Interpreter”→“+（install）”→“输入pyqt4”，安装即可。

2、在pyqt4的安装目录：C:\Users\zg\AppData\Local\Programs\Python\Python36\Lib\site-packages\PyQt4下，找到应用程序启动即可。

3、启动designer.exe程序后，进入Qt设计师主界面，就可以开始你的GUI设计之路了。。

4、选择“Main window”窗体，创建~

5、接下来是重点，pyqt4提供了直接将ui文件转为py文件的功能，非常实用，具体方法为：

编辑好ui界面后，点击保存（最好保存在C:\Users\zg\AppData\Local\Programs\Python\Python36\Scripts目录下），终端执行命令：pyuic4 xxx.ui -o xxx.py即可生成py代码文件xxx.py。

6、根据生成的py代码文件，再进行进一步的功能实现，下面贴出我的GUI界面及代码，仅供参考学习~

一个简单的文本处理工具，实现接口报文的转换与生成

代码如下：
