的Python（2.7）：压痕

Question

的Bug类程序错误每当我编译我的代码

import pygame,sys 
from classes import * 
pygame.init() 
SCREENWIDTH,SCREENHEIGHT = 640, 360 
screen = pygame.display.set_mode ((SCREENWIDTH, SCREENHEIGHT)) 
clock = pygame.time.Clock() 
FPS = 24 
bug = Bug(0,100,40,40,"bug.png") 
while True: 
    # PROCESSING 
    for event in pygame.event.get(): 
     if event.type == pygame.QUIT: 
      pygame.quit() 
      sys.exit() 
    #LOGIC 
    bug.motion() 
    #LOGIC 
    #DRAW 
    screen.fill((0,0,0)) 
    BaseClass.allsprites.draw(screen) 
    pygame.display.flip() 
    #DRAW 
    clock.tick(FPS) 

它显示了以下错误：

文件 “practice.py”，第16行 bug.motion（ ） ^ IndentationError：取消缩进不匹配任何外部缩进级别

每一行sys.exit()后有五个空格，当他们应该有四个。现在

import pygame,sys 
from classes import * 
pygame.init() 
SCREENWIDTH,SCREENHEIGHT = 640, 360 
screen = pygame.display.set_mode ((SCREENWIDTH, SCREENHEIGHT)) 
clock = pygame.time.Clock() 
FPS = 24 
bug = Bug(0,100,40,40,"bug.png") 
while True: 
    # PROCESSING 
    for event in pygame.event.get(): 
     if event.type == pygame.QUIT: 
      pygame.quit() 
      sys.exit() 
    #LOGIC 
    bug.motion() 
    #LOGIC 
    #DRAW 
    screen.fill((0,0,0)) 
    BaseClass.allsprites.draw(screen) 
    pygame.display.flip() 
    #DRAW 
    clock.tick(FPS)
