openmv进行扫码检测然后在将检测的结果进行对比然后控制舵机为什么显示语法错误啊就比如这段代码 如果检测结果为上海舵机

from pyb import Servo import time import sensor, image, time sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QVGA) sensor.skip_frames(time = 2000) sensor.set_auto_gain(False) # 必须关闭此功能,以防止图像冲洗… clock = time.clock() while(True): clock.tick() img = sensor.snapshot() img.lens_corr(1.8) # 1.8的强度参数对于2.8mm镜头来说是不错的。 for code in img.find_qrcodes(): img.draw_rectangle(code.rect(), color = (255, 0, 0)) message = code.payload() print(message) print(clock.fps()) s1 = Servo(1) # servo on position 1 (P7) while(1): if str((payload()) = 'shanghai' s1.angle(90) # move to 45 degrees time.sleep_ms(600) s1.angle(45) # move to -60 degrees in 1500ms time.sleep_ms(600) s1.angle(0) # move to 45 degrees time.sleep_ms(600) s1.angle(-45) # move to -60 degrees in 1500ms time.sleep_ms(600) s1.angle(-60) # move to 45 degrees time.sleep_ms(600) s1.angle(-90) # move to -60 degrees in 1500ms time.sleep_ms(600) #s1.speed(25) # for continuous rotation servos

31行后面没有冒号。
32行到45行应该有缩进。另外一个逻辑错误,代码有两个死循环。29行的后面永远不会运行。
