在QT designer中，我可以将文本标签设置为文本+ python脚本中的变量吗？

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

class MyWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.label = QLabel("Initial Text", self)
        self.label.setAlignment(Qt.AlignCenter)
        self.setCentralWidget(self.label)

        self.variable = "Variable Value"

        # Connect the variable with the label
        self.update_label()

    def update_label(self):
        self.label.setText(f"Text + {self.variable}")

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