利用pyuic5将ui文件转换为py文件的方法

import sys
 
 
if __name__ == "__main__":
  app = QtWidgets.QApplication(sys.argv) # 创建一个QApplication，也就是你要开发的软件app
  MainWindow = QtWidgets.QMainWindow()  # 创建一个QMainWindow，用来装载你需要的各种组件、控件
  ui = Ui_Form()             # ui是你创建的ui类的实例化对象
  ui.setupUi(MainWindow)         # 执行类中的setupUi方法，方法的参数是第二步中创建的QMainWindow
  MainWindow.show()            # 执行QMainWindow的show()方法，显示这个QMainWindow
  sys.exit(app.exec_())          # 使用exit()或者点击关闭按钮退出QApplication
