如果子程序输出3个数如何让它变成数组形式？

import sensor, image, time

thresholds = [(30, 100, 15, 127, 15, 127),
(8, 23, -27, -5, 2, 19),
(0, 27, -10, 17, -20, 3)]

sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(time = 2000)
sensor.set_auto_gain(False)
sensor.set_auto_whitebal(False)
clock = time.clock()

while(True):
clock.tick()

img = sensor.snapshot()
img.lens_corr(1.8)

for blob in img.find_blobs(thresholds, pixels_threshold=200, area_threshold=200):
img.draw_rectangle(blob.rect())
img.draw_cross(blob.cx(),blob.cy())

    print(blob.cx())

怎么用中心坐标实现？？

如何在多颜色识别模块以后进行从左到右按颜色排序
