Solve the following python programming problem given the following code:
def __init__(self, text = '', ok = 'Ok', cancel = 'Cancel', window = None, batch = None, group = None, theme = None, on_ok = None, on_cancel = None) : 
    def on_ok_click(_) : 
        if (on_ok is not None) : 
            on_ok (self) 
self.delete () 
def on_cancel_click(_) : 
        if (on_cancel is not None) : 
            on_cancel (self) 
self.delete () 
Manager.__init__ (self, content = Frame (VerticalContainer ([Label (text), HorizontalContainer ([Button (ok, on_press = on_ok_click), None, Button (on_cancel, on_press = on_cancel_click)])])), window = window, batch = batch, group = group, theme = theme, is_movable = True) 

    
    

    Fix the buggy line: Manager.__init__ (self, content = Frame (VerticalContainer ([Label (text), HorizontalContainer ([Button (ok, on_press = on_ok_click), None, Button (on_cancel, on_press = on_cancel_click)])])), window = window, batch = batch, group = group, theme = theme, is_movable = True)
