We can set visibility status of label using setVisible() method in PyQt5. In order to check the visibility status of any label we will use isVisible() method, this will return True or False by checking if the label is visible or not.

Note : If this method is used inside the constructor it will always return False as once the main-window/parent is visible only then the label visible property is changed to true.

Syntax : label.isVisible()

Argument : It takes no argument.

Return : It returns bool.

Code :

# 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 visibility status 
        self.label_1.setVisible(True) 
  
        # show all the widgets 
        self.show() 
  
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# getting visibility status 
visible = str(window.label_1.isVisible()) 
  
# printing visibility status of label 
print(visible) 
  
# start the app 
sys.exit(App.exec())
