How to remove item from QListWidget?

Question

Python

PyQt5

They helped me a lot with the creation of a graph shell, but I can not figure out how to remove those objects that seem to be created in a function

makeItem

in class

ListWidget

the code :

import sys
import requests
from PyQt5 import QtCore, QtWidgets, QtGui
from PyQt5.Qt import *


class Widget(QWidget):
    def __init__(self, urls):
        super().__init__()

        self.grid = QGridLayout(self)

        for i, url in enumerate(urls):
            lbl = QLabel()
            image = QImage()
            image.loadFromData(requests.get(url).content) 
            if i == 0:
                lbl.setPixmap(QPixmap(image).scaled(210, 210)) 
                self.grid.addWidget(lbl, i+1, 0, 4, 1)
            else:
                lbl.setPixmap(QPixmap(image).scaled(70, 70)) 
                self.grid.addWidget(lbl, i, 1, 1, 1)        


class ListWidget(QListWidget):
    def __init__(self, *args, **kwargs):
        super(ListWidget, self).__init__(*args, **kwargs)
        self.setHorizontalScrollBarPolicy(Qt.ScrollBarAlwaysOff)
        self.setEditTriggers(self.NoEditTriggers)
        self.setFlow(self.LeftToRight)
        self.setWrapping(True)
        self.setResizeMode(self.Adjust)
        self.setSpacing(10)
        # Резиновая лента (для эффекта выбора рамки)
        self._rubberPos  = None
        self._rubberBand = QRubberBand(QRubberBand.Rectangle, self)

    def makeItem(self, lb):
        item = QtWidgets.QListWidgetItem(self)
        item.setSizeHint(QtCore.QSize(300, 300))
        self.setItemWidget(item, lb)


class MyWindow(QtWidgets.QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('ListWidget')
        self.resize(1100, 670)
        self.show()        
        
        self.listWidget = ListWidget()

        box = QtWidgets.QVBoxLayout(self)
        box.addWidget(self.listWidget)

        self.urls = [
            "https://img.icons8.com/ios/452/phone.png",
            "https://img.icons8.com/ios/452/phone.png",

            "https://laguna-akul.ru/upload/003/u379/f4/61/8f68d93a.jpg",
        ]
        
        num = 5                                                
        for i in range(num):
            art = Widget(self.urls)            
            self.listWidget.makeItem(art)        
            QApplication.processEvents() 
        

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    w = MyWindow()
    sys.exit(app.exec_())

It seems like takeitem or removeItemWidget should be used here, I tried both but didn't get any result.

Answer 1

And where is the part of the code that is responsible for the removal? How is it called?
takeItem(row) - takeItem removes the widget item from the list and returns it

import sys
# import requests
from PyQt5 import QtCore, QtWidgets, QtGui
from PyQt5.Qt import *
