button.whatsThis()

whatsThis returns string.

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
  
class Window(QMainWindow):
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
  
        # creating a push button
        button = QPushButton("CLICK", self)
  
        # setting geometry of button
        button.setGeometry(200, 150, 100, 40)
  
        # adding action to a button
        button.clicked.connect(self.clickme)
  
        # creating the help text
        button.setWhatsThis("this is a push button \
                          linked to clickme function")
  
        # getting the help text
        help = button.whatsThis()
  
        # creating label to print help text
        label = QLabel(help, self)
        label.adjustSize()
        label.move(200, 200)
  
    # action method
    def clickme(self):
  
  
        # printing pressed
        print("pressed")
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
