我想用pyqt5创建一个浏览按钮，但我不明白

from PyQt5 import QtWidgets,QtCore, QtGui

import test3 

class MyWindow(QtWidgets.QMainWindow):

    def __init__(self, parent=None):
        QtWidgets.QMainWindow.__init__(self, parent)
        self.ui = test3.Ui_MainWindow()
        self.ui.setupUi(self)

        self.ui.pushButton_2.clicked.connect(self.getfiles)


    def getfiles(self):
        fileName = QtGui.QFileDialog.getOpenFileName(self,'Single File','C:\'','*.xlsm')
        self.ui.lineEdit.setText(fileName)


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