如何将矩形r中的w和h赋值给一个新的变量

[scm4]

import sensor, image, time

sensor.reset()
sensor.set_pixformat(sensor.GRAYSCALE) # 灰度更快(160x120 max on OpenMV-M7)
sensor.set_framesize(sensor.QQVGA)
sensor.skip_frames(time = 2000)
clock = time.clock()

while(True):
    clock.tick()
    img = sensor.snapshot()
    

    # 下面的`threshold`应设置为足够高的值，以滤除在图像中检测到的具有
    # 低边缘幅度的噪声矩形。最适用与背景形成鲜明对比的矩形。

    for r in img.find_rects(threshold = 10000):
       
        img.draw_rectangle(r.rect())
       
        print('you send:',r)#写到串口监视端，让你能够看到数据

w = r.w()
h = r.h()
print(w,h)
