Call a function value from another python file - APP crashes

Hi, I am trying to get a value from a function that is in another python file. Whenever I try to get the value app crashes. I have attached the code for reference.
class Ui_MainWindow(QObject): def setupUi(self, MainWindow): .................................UI code ............................. self.casesecondbutton.clicked.connect(self.casesecondbutton_click) @pyqtSlot( ) def casesecondbutton_click(self): casesecondlabel = self.casesecondline.toPlainText() print(casesecondlabel) return casesecondlabel
I have two buttons. One is for storing a value in a variable. Another b utton is for getting the stored value. I am using two buttons since I need to perform some other operations.
In this MyApp.py file. I am calling the function value. It is crashing.
from mainwindow import Ui_MainWindow class MainWindowUIClass( Ui_MainWindow ): def __init__( self ): super().__init__() def loadfromdbbutton_click(self): name = Ui_MainWindow.casesecondbutton_click() print(name)
For clear understanding. I have a textedit where I can enter a value. After entering and pressing casesecondbutton the value gets stores in casesecondlabel. After pressing loadfrombutton it should get the value for me. I need to use it in for upcoming codes.

Do you even call
self.casesecondbuttonalready set up as a button at the time you call
name = Ui_MainWindow.casesecondbutton_click()? [I'm not sure in Python that
Ui_MainWindow.casesecondbutton_click()is correct, does it make any difference if you go
self.casesecondbutton_click()?] Run your code in a debugger and discover exactly which line it is on when it "crashes".
I don't know what you are trying to do here, but I'm afraid the code is all wrong. Slots do not return values. You do not want to call
loadfromdbbutton_click(). I don't know why you have a separate
