Pygame.draw.rect無效語法

Question

即使我複製粘貼了命令語法並放置了我的變量，但我在pygame.draw.rect(screen, (0, 255, 0), (200, 150, 100, 50), 2) 上遇到錯誤。

#! /usr/bin/env python 
import pygame, sys 
from pygame.locals import * 
clock = pygame.time.Clock() 
LEFT=1 
width= 1000 
height=500 
running =1 
x = 0 
y = 0 
isdown = False 
screen = pygame.display.set_mode((width, height)) 
while running: 
    for event in pygame.event.get(): 
     #screen.fill((90,90,90)) 
     if event.type == pygame.QUIT: 
      running=0 
     if event.type ==pygame.MOUSEBUTTONDOWN and event.button== LEFT: 
      isdown = True 
      t=event.pos 
      x,y=t 
     if event.type == pygame.MOUSEMOTION: 
      if isdown: 
       t=event.pos 
       x,y=t 
     if event.type ==pygame.MOUSEBUTTONUP and event.button== LEFT: 
      isdown=False 
    if isdown: 
     #rect= ((32*int(x/32),(32*int(y/32)),32,32) 
     pygame.draw.rect(screen,(0,255,0),(200,150,100,50),2) 
    clock.tick(3000) 
    pygame.display.flip() 

錯誤：

File "PATH(not giving it)", line 30 
    pygame.draw.rect(screen,(0,255,0),(200,150,100,50),2) 
     ^
SyntaxError: invalid syntax

正如我看看吧，我覺得上面犯錯誤pygame.draw通話，#rect= ((32*int(x/32),(32*int(y/32)),32,32)行，實際上是不是在你的代碼的註釋。它在開頭處有一個額外的(，導致在以下行上出現pygame.rect的語法錯誤。
