其实应用pangu做文本格式标准化的业务代码在之前就实现了，次要可能将中文文本文档中的文字、标点符号等进行标准化。

然而为了不便起来咱们这里应用了Qt5将其做成了一个能够操作的页面利用，这样不相熟python的敌人就能够不必写代码间接双击运行应用就OK了。
为了使文本格式的丑化过程不影响主线程的应用，顺便采纳QThread子线程来专门的运行文本文档丑化的业务过程，接下来还是采纳pip的形式将所有须要的非标准模块装置一下。
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pangupip install -i https://pypi.tuna.tsinghua.edu.cn/simple PyQt5将咱们应用到的pyqt5利用制作模块以及业务模块pangu导入到咱们的代码块中。
# It imports all the classes, attributes, and methods of the PyQt5.QtCore module into the global symbol table.from PyQt5.QtCore import *# It imports all the classes, attributes, and methods of the PyQt5.QtWidgets module into the global symbol table.from PyQt5.QtWidgets import QApplication, QWidget, QHBoxLayout, QVBoxLayout, QTextBrowser, QLineEdit, QPushButton, \ QFormLayout, QFileDialog# It imports all the classes, attributes, and methods of the PyQt5.QtGui module into the global symbol table.from PyQt5.QtGui import QIcon, QFont, QTextCursor# It imports the pangu module.import pangu# It imports the sys module.import sys# It imports the os module.import os为了缩小python模块在打包时资源占用过多，打的exe应用程序的占用空间过大的状况，这次咱们只导入了可能应用到的相干python类，这个小细节大家留神一下。
上面创立一个名称为PanGuUI的python类来实现对整个利用页面的开发，将页面的布局以及组件相干的局部写到这个类中。并且给页面组件绑定好相应的槽函数从而实现页面的'点击'等性能。
