def pbClicked(self): self.fileName = QFileDialog.getOpenFileNames(None, " Please select the file to add ", "E:\Program Files (x86)\PycharmProjects\nn\wangyiyun", "Text Files (*.xls);;All Files (*)") return self.fileName

I was thinking about this filename This variable can be passed to another py In the document , And can output

def pbClicked(self): self.fileName = QFileDialog.getOpenFileNames(None, " Please select the file to add ", "E:\Program Files (x86)\PycharmProjects\nn\wangyiyun", "Text Files (*.xls);;All Files (*)") return self.fileNamedef pbClicked2(self): os.system('python test2.py')

Just click the second button , And then run test2.py file , And then in test2.py In the file, you can get the file path returned by the first button to open the file

Here is test2.py

import Qtdesigner.untitled as tsfrom Qtdesigner.untitled import Ui_MainWindowfilename = Ui_MainWindow.pbClicked()print(filename)

But this Ui_MainWindow.pbClicked(), Report errors Parameter 'self' unfilled
