代码：

# importing the required libraries
  
from PyQt5.QtCore import * 
from PyQt5.QtGui import * 
from PyQt5.QtWidgets import * 
import sys
  
  
class Window(QMainWindow):
    def __init__(self):
        super().__init__()
  
  
        # set the title
        self.setWindowTitle("Python")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # creating a label widget
        self.label_1 = QLabel("Label", self)
  
        # moving position
        self.label_1.move(0, 0)
  
        # setting up the border
        self.label_1.setStyleSheet("border :3px solid black;")
  
        # setting label tool tip
        self.label_1.setToolTip("It is for 5 seconds")
  
        # setting time duration
        self.label_1.setToolTipDuration(500)
  
        # getting tool tip duration
        t = str(self.label_1.toolTipDuration())
  
        # creating a label widget
        self.label_2 = QLabel("label tool tip duration =" + t + "ms", self)
  
        # moving position
        self.label_2.move(0, 50)
  
        # adjust size
        self.label_2.adjustSize()
  
        # show all the widgets
        self.show()
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
