PyQt5 QListWidget – Getting Count of Items

In this article we will see how we can get the count of items of the QListWidget. QListWidget is a convenience class that provides a list view with a classic item-based interface for adding and removing items. QListWidget uses an internal model to manage each QListWidgetItem in the list. Count property holds the number of items in the list including any hidden items.

In order to do this we will use count method with the list widget object. 
Syntax : list_widget.count() 
Argument : It takes no argument 
Return : It returns integer

Below is the implementation 

Python3

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
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, 500, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()



    # method for components
    def UiComponents(self):

        # creating a QListWidget
        list_widget = QListWidget(self)

        # setting geometry to it
        list_widget.setGeometry(70, 70, 100, 30)

        # list widget items
        item1 = QListWidgetItem("A")
        item2 = QListWidgetItem("B")
        item3 = QListWidgetItem("C")

        # adding items to the list widget
        list_widget.addItem(item1)
        list_widget.addItem(item2)
        list_widget.addItem(item3)

        # creating a label
        label = QLabel("GeeksforGeeks", self)

        # setting geometry to the label
        label.setGeometry(200, 100, 300, 80)

        # making label multi line
        label.setWordWrap(True)

        # getting count of the items of list widget
        value = list_widget.count()

        # setting text to the label
        label.setText("Item Count : " + str(value))



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
