Python用户界面不工作。

我已使用pyuic4将.ui文件转换为.py文件。但是当我用python运行代码时，什么都没有发生。没有错误，没有用户界面。代码在一秒钟内运行并结束。我尝试使用print命令进行调试，python没有进入def setupUiself，Frame:或def retranslateUiself，Frame: 我做错了什么？谢谢你的帮助

from PyQt4 import QtWebKit

添加以下内容：

if __name__ == "__main__":
   app = QtGui.QApplication(sys.argv)
   f=QtGui.QMainWindow()
   w = Ui_MainWindow()

   w.setupUi(f)
   f.show()
   sys.exit(app.exec_())

我知道您已经定义了几个函数，但是您似乎没有调用它们中的任何一个。请记住：除非调用函数，否则函数不会执行任何操作。错误之处在于未能阅读PyQt文档：例如。
