I have written a simple code of python GUI for sleeping my code for 10 seconds. At the same time, the GUI should run without freezing. Is not possible by defining primari thready and secondary thread? While I click on "Run" button pythonw.exe has stopped working. Does anyone have any thoughts on how I may be able to troubleshoot this? Thank you.

class Window(QtGui.QMainWindow):
def __init__(self):
super(Window,self).__init__()
self.setGeometry(400,150, 550, 500)
self.setWindowTitle("my first program")
self.home()
def home(self):
self.button_1 = QtGui.QPushButton('Run', self)
self.button_1.resize(60,25)
self.button_1.move(230,230)
self.button_1.clicked.connect(self.Thread_test)
self.textbox_1 = QTextEdit(self)
self.textbox_1.move(15,290)
self.textbox_1.resize(510,170)
self.show()
def Thread_test(self):
t = threading.Thread(target=self.calculation)
t.start()
def calculation(self):
msg="program is working"
self.textbox_1.setText(msg)
time.sleep(5)
msg="program was slept for few sec."
self.textbox_1.setText(msg)
def run():
app=QtGui.QApplication(sys.argv)
GUI=Window()
sys.exit(app.exec_())
run()
