I had thought the same workaround but unfortunately loop is already
under a def ;

def writeWaveform(self, fo, header=''):
        data1 = numpy.zeros(self.size)
        screen = pygame.display.set_mode((0, 0), pygame.FULLSCREEN)
        timer = pygame.time.Clock()
        white = True
        fo.write(header)
        start = time.time()
        end = time.time() - start
        while(end<10):
	  data1 = self.chan1.getWaveform()
	  end = time.time() - start
	  timer.tick(10) #FPS
	  screen.fill((255,255,255) if white else(0,0,0))
	  white = not white
	  pygame.display.update()
	  for i in range(self.size):
	      end = time.time() - start
	      f.write("%3.8f\t%f\n"%(end,data1[i]))
