执行以下程序报错：app = QtGui.QApplication(sys.argv)
AttributeError: 'module' object has no attribute 'QApplication'


from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(400, 300)
        self.label = QtWidgets.QLabel(Dialog)
        self.label.setGeometry(QtCore.QRect(60, 130, 54, 12))
        self.label.setObjectName("label")
        self.pushButton = QtWidgets.QPushButton(Dialog)
        self.pushButton.setGeometry(QtCore.QRect(150, 200, 75, 23))
        self.pushButton.setObjectName("pushButton")
        self.lineEdit = QtWidgets.QLineEdit(Dialog)
        self.lineEdit.setGeometry(QtCore.QRect(140, 130, 113, 20))
        self.lineEdit.setObjectName("lineEdit")

        self.retranslateUi(Dialog)
        self.pushButton.clicked.connect(self.lineEdit.clear)
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
        self.label.setText(_translate("Dialog", "TextLabel"))
        self.pushButton.setText(_translate("Dialog", "clear"))

if __name__ == '__main__':
    import sys
    app = QtGui.QApplication(sys.argv)
    From = QtGui.QWidget()
    ui = Ui_Dialog()
    ui.setupUi(Form)
    Form.show()
    sys.exit(app.exec_())

在PyQt5中，
“app = QtGui.QApplication(sys.argv)”改为：
“app = QtWidgets.QApplication(sys.argv)”
