I正在用python编写代码（Vs code），我遇到了这个错误：

Expected ")"  Pylance

错误发生在：def main()
我试着运行我的主程序并把它打印到我的屏幕上。我在谷歌上搜索了一下，没有找到任何解决方案。我该怎么解决这个问题呢？
这是我的代码：

#The main driver of our code , this will handle user input and updating the graphics 
def main():  

   p.init ()
   screen = p.display.set_mode((WIDTH,HEIGHT))
   clock = p.time.Clock ()
   screen.fill(p.Color("white"))
   gs= ChessEngine.GameState()
   print(gs.board)
   loadImages() #only do this once, before the whille loop
   running=True
   while running :
    for e in p.event.get():
     if e.type == p.QUIT:
      running =False
 
   drawGameState(screen,gs)
   clock.tick(MAX_FPS)
   p.display.flip() 

 '''

 '''
 def drawGameState(screen,gs):
  drawBoard (screen) #draw squars on the board
 #add in piece highlighting or move suggestions
 
 drawPieces(screen,gs.board) #draw pieces on the top of those squares

'''
draw the squares on the board the top left square is always light

'''
def drawBoard(screen):
 colors = [p.Color("white"), p.Color("gray")]
 for r in range (DIMENSION):
   for c in range (DIMENSION):
    color = colors[((r+c) % 2)]
    p.draw.rect(screen , color , p.Rect(c*SQ_SIZE,r*SQ_SIZE,SQ_SIZE_SQ_SIZE))

'''
draw the pieces on the board using the current Game.State.board
'''
def drawPieces(screen,board):
    for r in range (DIMENSION):
        for c in range (DIMENSION):
            piece=board[r][c]
            if piece != "--": #not empty squares
                screen.blit(IMAGES[piece],p.Rect(c*SQ_SIZE,r*SQ_SIZE))
 

if __name__ == '__main__':
   main()
