SyntaxError "nessuna alternativa valida sull'ingresso 'sé'"

Question

Ho un file gui.py contenente il codice seguente:

from javax.swing import JFrame, JPanel, Box, JComboBox, JSpinner, JButton, JLabel, SpinnerNumberModel, WindowConstants 
from java.awt import BoxLayout, GridLayout 

class SettingsWindow: 

    def start(self): 
     selected = self.combobox.selectedIndex 
     if selected >= 0: 
      self.map = self.map_list[ selected ] 
     self.games = self.spinner.getValue() 

    def __init__(self, map_list): 
     frame = JFrame("Settings") 
     frame.setSize(200, 250) 
     frame.setLayout(BoxLayout()) 
     panel = JPanel(GridLayout(3, 1) 

     # Map Combobox 
     self.map_list = map_list 
     self.combobox = JComboBox(self.map_list) 
     map_box = Box(BoxLayout.X_AXIS) 
     map_box.add(JLabel("Select map file:")) 
     map_box.add(Box.createHorizontalStrut(15)) 
     map_box.add(self.combobox) 
     panel.add(map_box) 

     # Games Spinner 
     self.spinner = JSpinner(SpinnerNumberModel(1, 1, 25, 1)) 
     games_box = Box(BoxLayout.X_AXIS) 
     games_box.add(JLabel("Number of games:")) 
     map_box.add(Box.createHorizontalStrut(15)) 
     games_box.add(self.spinner) 
     panel.add(games_box) 

     # Start Button 
     btn = JButton("Start", actionPerformed = self.start) 
     btn_box = Box(BoxLayout.X_AXIS) 
     btn_box.add(btn) 
     panel.add(btn_box) 

     frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE) 
     frame.setVisible(True) 

    if __name__ == '__main__': 
     SettingsWindow() 

Poi, nel mio file principale, che io chiamo la classe superiore con questo codice:

settings = gui.SettingsWindow(map_list) 

E ottengo l'errore:

SyntaxError (("no viable alternative at input 'self'", ('.../gui.py', 19, 8, '  self.map_list = map_list\n'))) 

Se chiunque può vedere ciò che mi manca, sarei davvero grato per l'aiuto!

Hai dimenticato di chiudere il paren sulla riga di codice precedente.
