我正在尝试创建一个迷宫界面，其中两个刺激在左右两侧闪烁。代码运行，打开界面并立即关闭。我知道这是因为循环运行不正常。由于我是Python的初学者，我无法真正找到bug的位置。
任何人都可以看看并帮我解决此错误吗？

这是另一个名为flicky.py的模块的片段，我在主代码中调用了它：
class FlickyManager:
def __init__(self,screen):
self.flickies = []
self.screen = screen
def addFlicky(self,f):
self.flickies.append(f)
def add(self,location,frames):
w, h = self.screen.get_size()
if location == 'left':
x = 0; y = h / 2 - A/2;
elif location == 'right':
x = w - A; y = h / 2 - A/2;
elif location == 'top':
y = 0; x = w / 2 - A/2;
elif location == 'bottom':
y = h-A; x = w / 2 - A/2;
else:
raise ValueError("location %s unknown" % location)
f = Flicky(x,y,frames)
self.flickies.append(f)
def process(self):
for f in self.flickies:
f.process()
def draw(self):
for f in self.flickies:
f.draw(self.screen)
这定义了大脑模块：
def headto( ):
board.start_streaming(getsample, 1.5)
average7_5 = numpy.mean(e7_5Output)
average12_5 = numpy.mean(e12_5Output)
print average7_5
print average12_5
average = (average7_5 + average12_5)/2
print average
if 10000 < average < 30000:
return "right"
elif 30000 <= average < 60000:
return "left"
else:
return "stay"
对不起这里的烂摊子。但基本上我要做的是将以下两个包合二为一。在中间有一个迷宫屏幕，在左边和右边有两个闪烁的板。我能够成功地逐个运行包，但是当我合并时，它不能一起显示。我只是编码的初学者，这就是代码混乱的原因。
这是第一个包，两个刺激闪烁：
import pygame #@UnusedImport
from flicky import FlickyManager
pygame.init()
screen=pygame.display.set_mode([800,200])
pygame.display.set_caption("Stimulus")
done=False
clock=pygame.time.Clock()
flickymanager = FlickyManager(screen)
# 7.5 Hz
flickymanager.add('left',8.33)
# 12. 5 Hz
flickymanager.add('right',5)
while done==False:
for event in pygame.event.get():
if (event.type == pygame.KEYUP) or (event.type == pygame.KEYDOWN):
if (event.key == pygame.K_ESCAPE):
done = True
if event.type == pygame.QUIT:
done = True
screen.fill((0,0,0))
clock.tick(60) # 16 ms between frames ~ 60FPS
flickymanager.process()
flickymanager.draw()
pygame.display.flip()
pygame.quit()
这是迷宫布局的第二个包。

gameDisplay.blit(blockImg,( 200 + bx * 40 , 40 + by * 40 ))
bx = bx + 1
if bx == M:
bx = 0
by = by + 1
while not exit:
for event in pygame.event.get():
if event.type == pygame.QUIT:
exit = True
if brain.headto() == 'right':
x_change = 20
elif brain.headto() == 'left':
x_change = -20
elif brain.headto() == 'stay':
x_change = 0
x += x_change
gameDisplay.fill(white)
player(x,y)
maze()
pygame.display.update()
pygame.quit()
quit()
任何人都可以帮我弄清楚如何将这两者合二为一吗？对我来说，只有两块板的屏幕是唯一的。我无法显示迷宫画面。任何帮助都会很棒。在此先感谢！

该行中存在语法错误：
while (given > 0){
remainder = given % base;
if (remainder >= 10){
switch(remainder){
case 10:output = "A" + output;break;
case 11:output = "B" + output;break;
case 12:output = "C" + output;break;
case 13:output = "D" + output;break;
case 14:output = "E" + output;break;
case 15:output = "F" + output;break;
}
} else {
output = remainder + output;
}
given /= base;
}
System.out.println(output);
应该是：
while not exit and while done == False:
在绘制第while not exit and not done:行时，它引用的screen.fill((0,0,0))不存在，我认为您想要使用screen。
gameDisplay也从未定义过，因此在调用brain时会抛出错误。
brain.headto()似乎也从未被定义过。
这些问题导致程序在启动后立即崩溃。 要查看导致程序崩溃的任何错误，请通过IDLE或IDE运行代码，而不是运行.py文件，因为这通常会提供有关崩溃的反馈。
此外，建议使用除blockImg以外的其他变量名，因为这在python中具有特殊含义。

检查此示例是否按预期工作。我无法使用brain模块对其进行测试，只是使用了箭头键。
