如何让PyQt5 QPushButton在不同的按钮点击上执行不同的命令

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

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

    def initUI(self):
        # 设置窗口标题和大小
        self.setWindowTitle("Button Example")
        self.setGeometry(100, 100, 300, 200)

        # 创建按钮对象
        button1 = QPushButton("Button 1", self)
        button1.clicked.connect(self.button1Clicked)

        button2 = QPushButton("Button 2", self)
        button2.clicked.connect(self.button2Clicked)

    def button1Clicked(self):
        # Button 1的点击事件处理函数
        print("Button 1 clicked")

    def button2Clicked(self):
        # Button 2的点击事件处理函数
        print("Button 2 clicked")

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