PyQt5-通过Python脚本把当前目录下的所有.ui文件转换为.py文件

环境

操作系统: Windows 10 专业版 64-bit (10.0, Build 16299) (16299.rs3_release.170928-1534)
Python Version: 3.7.1
PyQt5 Version: 5.11.3
Qt Designer Version: 5.11.2

python脚本代码如下(将当前目录下的所有.ui文件转为.py文件)

import os
import os.path

# UI 文件所在的路径
dir = \'./\'

# 列出目录下的所有 UI 文件
def listUiFile():
	list = []
	files = os.listdir(dir)
	for filename in files:
		#print(dir + os.sep + f)
		#print(filename)
		if os.path.splitext(filename)[1] == \'.ui\':
			list.append(filename)
	
	return list

# 把扩展名为.ui的成扩展名为.py的文件
def transPyFile(filename):
	return os.path.splitext(filename)[0] + \'.py\'

# 调用系统命令把 UI 文件改成扩展名为 Python 文件
def runMain():
	list = listUiFile()
	for uifile in list:
		pyfile = transPyFile(uifile)
		cmd = \'pyuic5 -o {pyfile} {uifile}\'.format(pyfile=pyfile, uifile=uifile)
		#print(cmd)
		os.system(cmd)

# 程序的入口
if __name__ == \'__main__\':
	runMain()

窗体截图如下

原.ui文件内容如下

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>MainWindow</class>
 <widget class="QMainWindow" name="MainWindow">
  <property name="geometry">
   <rect>
    <x>0</x>
    <y>0</y>
    <width>800</width>
    <height>600</height>
   </rect>
  </property>
  <property name="windowTitle">
   <string>MainWindow</string>
  </property>
  <widget class="QWidget" name="centralwidget">
   <widget class="QPushButton" name="pushButton">
    <property name="geometry">
     <rect>
      <x>330</x>
      <y>200</y>
      <width>91</width>
      <height>51</height>
     </rect>
    </property>
    <property name="text">
     <string>PushButton</string>
    </property>
   </widget>
  </widget>
  <widget class="QMenuBar" name="menubar">
   <property name="geometry">
    <rect>
     <x>0</x>
     <y>0</y>
     <width>800</width>
     <height>23</height>
    </rect>
   </property>
  </widget>
  <widget class="QStatusBar" name="statusbar"/>
 </widget>
 <resources/>
 <connections/>
</ui>

转换后的 .py 文件如下
