如何将Python控制台程序(包括while true循环)转换为PyQt？

from PyQt5 import QtCore, QtGui, QtWidgets

class MainWindow(QtWidgets.QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()

        self.setWindowTitle("My Application")
        self.setGeometry(100, 100, 500, 500)
        
        self.label = QtWidgets.QLabel("Hello World", self)
        self.label.setGeometry(QtCore.QRect(100, 100, 200, 50))

        self.timer = QtCore.QTimer()
        self.timer.timeout.connect(self.update_label)
        self.timer.start(1000)
        
    def update_label(self):
        # 控制台程序的逻辑代码
        print("Hello World")

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