识别二维码，之后进行判断

[a2bm]

我想先进行识别二维码，扫描出二维码的内容之后根据内容进行判断应该如何写

import sensor, image,pyb,time
from pyb import UART
from pyb import Pin
uart = UART(3, 9600)
led1 = pyb.LED(1)
led2 = pyb.LED(2)
led3 = pyb.LED(3)
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QQVGA) # can be QVGA on M7...
sensor.skip_frames(30)
sensor.set_auto_gain(False) # must turn this off to prevent image washout...

while(True):
       img = sensor.snapshot()
       img.lens_corr(1.8) # strength of 1.8 is good for the 2.8mm lens.
       for code in img.find_qrcodes():
         xingxi = code.payload()
         print(xingxi)
         uart.write(xingxi)

这是代码，例如：识别出二维码内容是123+123，让红灯亮，识别出内容321+321让绿灯亮。判断的程序应该怎么写

    for code in img.find_qrcodes():
        xingxi = code.payload()
        print(xingxi)
        if xingxi == '123+123':
            print('OK')
        else:
            print('NOT OK')
