在pyqt5组合框中显示两个值并传递这些值

from PyQt5.QtWidgets import QApplication, QComboBox, QWidget, QVBoxLayout
from PyQt5.QtCore import Qt

class MyWindow(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        layout = QVBoxLayout()
        self.setLayout(layout)

        # 创建组合框
        combo_box = QComboBox()
        layout.addWidget(combo_box)

        # 添加选项
        combo_box.addItem("值1")
        combo_box.addItem("值2")

        # 设置当前选中项
        combo_box.setCurrentIndex(0)

        # 绑定信号和槽函数
        combo_box.currentIndexChanged.connect(self.onComboBoxChanged)

    def onComboBoxChanged(self, index):
        # 获取当前选中项的值
        value = self.sender().currentText()
        print(value)

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