def pbClicked(self): self.fileName = QFileDialog.getOpenFileNames(None, "請選擇要添加的文件", "E:\Program Files (x86)\PycharmProjects\nn\wangyiyun", "Text Files (*.xls);;All Files (*)") return self.fileNamedef pbClicked2(self): os.system('python test2.py')就是點這個第二個按鈕，然後運行test2.py文件，然後在test2.py文件中能夠獲取到第一個按鈕打開文件返回的文件路徑
下面是test2.py
import Qtdesigner.untitled as tsfrom Qtdesigner.untitled import Ui_MainWindowfilename = Ui_MainWindow.pbClicked()print(filename)但是這個Ui_MainWindow.pbClicked()，報錯Parameter 'self' unfilled
