from mainwindow import Ui_MainWindow  #     form.py     


class mywindow(QtWidgets.QMainWindow, Ui_MainWindow):
    def __init__(self):
        super(mywindow, self).__init__()
        self.setupUi(self)

    #      
    def hello(self):
        self.textEdit.setText("hello world")

app = QtWidgets.QApplication(sys.argv)
window = mywindow()
window.show()
sys.exit(app.exec_())
