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![【Python】Python PYQT4 GUI编程与exe打包-LMLPHP]( "【Python】Python PYQT4 GUI编程与exe打包-LMLPHP")
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~

二、将py文件打包成exe文件
实现exe文件打包的工具很多，如：pyinstaller、py2exe、cxfreeze等，这里使用cxfreeze进行文件打包，直接使用pip install pyinstaller安装pyinstaller即可。
此时可以为exe文件添加自己想要的ico图标，方法如下：
注意：将ico文件放在py文件相同目录下，并修改xxx.spec文件（与xxx.py文件同一目录下，相同名字的spec文件）
打开终端，执行pyinstaller xxx.spec
生成exe文件~
笔者用cxfreeze进行过exe文件的打包，过程中发生了一下，特此记录一下~
①、安装cxfreeze完毕后，到安装目录C:\Users\zg\AppData\Local\Programs\Python\Python36\Scripts\pyinstaller下，运行命令行窗口，执行命令cxfreeze，若发生以下报错
②、需在该目录下，创建cxfreeze.bat文件，文件内容为
3、执行如下命令打包即可
cxfreeze xxx.py --target-dir=d:\dist\ --icon=d:\xxxx.ico
以上就是就是Python PYQT4的简单应用了，实现的功能比较简单，后续会在进行相应的功能优化，敬请期待~~~
