如何在PyQt5中删除Qlabel

from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel, QPushButton
from PyQt5.QtCore import Qt

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        
        self.label = QLabel("Hello World", self)
        self.label.setGeometry(50, 50, 200, 50)
        
        self.button = QPushButton("删除Label", self)
        self.button.setGeometry(50, 120, 100, 30)
        self.button.clicked.connect(self.delete_label)
        
    def delete_label(self):
        self.label.deleteLater()

if __name__ == "__main__":
    app = QApplication([])
    window = MainWindow()
    window.show()
    app.exec_()
