TypeError：參數1必須是pygame.Surface，而不是builtin_function_or_method（python 3.2.3）

Question

好吧，所以我使用pygame來創建程序，但是，當我嘗試創建我的矩形工具時，它似乎總是顯示TypeError：參數1必須是pygame.Surface，而不是builtin_function_or_method。我不知道爲什麼，因爲我問了一個同伴，它的工作非常好，使用相同的代碼。

from pygame import * 
from random import * 

screen = display.set_mode((1152,864)) 

start = 0,0 
color = (0,0,0) 
canvasRect = Rect(150,160,850,700) 
recttoolRect = Rect(20,350,40,40) 
draw.rect(screen,(255,255,255),canvasRect) 

running = True 
while running: 
    finish = False 
    for e in event.get(): 
     if e.type == QUIT: 
      running = False 

     if e.type == MOUSEBUTTONDOWN: 
      if e.button == 1: 
       start=e.pos 
       copy = screen.copy 

    mb = mouse.get_pressed() 
    mx,my = mouse.get_pos() 

    draw.rect(screen,(255,255,255),recttoolRect) 

    if mb[0] == 1 and recttoolRect.collidepoint(mx,my): 
     tool = rect 
    if mb[0] == 1 and canvasRect.collidepoint(mx,my) and tool == rect: 
     screen.set_clip(canvasRect) 
     screen.blit(copy,(0,0)) 
     draw.rect(screen,(colour),(start[0],start[1],mx-start[0],my-start[1])) 


    display.flip() 
quit()

沒有完整的追溯，很難說，但我猜你已經忘記了某個函數調用背後的一些括號。例如。如果rect是函數，則可能必須編寫rect()而不是rect。
