You can't have a slot like this:
MainWindow.btn.clicked.connect(MainWindow.txtbox.setText(test()))
because that's mean: "connect to the return of
MainWindow.txtbox.setText(test())" and it's not possible at this stage
of your program.
Use instead a function:
MainWindow.btn.clicked.connect(my_slot) # No parenthesis !
def my_slot():
MainWindow.txtbox.setText(test())
