如何使用for循环从PyQt5中的不同组合框中收集数据？

from PyQt5.QtWidgets import QApplication, QMainWindow, QComboBox, QPushButton

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

        self.combo_boxes = []
        self.button = QPushButton("Collect Data", self)
        self.button.clicked.connect(self.collect_data)

        # 创建三个组合框并添加到窗口中
        for i in range(3):
            combo_box = QComboBox(self)
            combo_box.addItem("Option 1")
            combo_box.addItem("Option 2")
            combo_box.addItem("Option 3")
            self.combo_boxes.append(combo_box)

    def collect_data(self):
        data = []
        # 使用for循环遍历所有组合框，收集选中的数据
        for combo_box in self.combo_boxes:
            selected_option = combo_box.currentText()
            data.append(selected_option)

        print(data)

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