如何在PyQt5标签中输入多个参数？

import sys
from PyQt5.QtWidgets import QApplication, QLabel, QVBoxLayout, QWidget, QLineEdit, QPushButton

app = QApplication(sys.argv)
window = QWidget()
layout = QVBoxLayout()
window.setLayout(layout)

line_edit1 = QLineEdit()
line_edit2 = QLineEdit()
line_edit3 = QLineEdit()
button = QPushButton("提交")

layout.addWidget(line_edit1)
layout.addWidget(line_edit2)
layout.addWidget(line_edit3)
layout.addWidget(button)

def handle_button_click():
    param1 = line_edit1.text()
    param2 = line_edit2.text()
    param3 = line_edit3.text()
    print("参数1:", param1)
    print("参数2:", param2)
    print("参数3:", param3)

button.clicked.connect(handle_button_click)

window.show()
sys.exit(app.exec_())
