为什么会发生这种情况我没有第 86 行

Question

我尝试了运行这个，我只是使用了空格而不是制表符，但是

import time
import sys
import numpy as np
import SimpleCV
import webiopi
from ayarlar import *

GPIO = webiopi.GPIO
GPIO.setFunction(4, GPIO.OUT)
GPIO.setFunction(17, GPIO.OUT)
GPIO.setFunction(18, GPIO.OUT)
GPIO.setFunction(27, GPIO.OUT)
GPIO.setFunction(10, GPIO.OUT)
GPIO.setFunction(25, GPIO.OUT)

def dist_from_color(img_color):
    matrix = (img.getNumpy()[:,:,[2,1,0]] - color) ** 2
    width, height = img.size()
    return matirx.sum() ** 0.5 / (width * height)

def forward():
   GPIO.digitalWrite(18, GPIO.HIGH)
   GPIO.digitalWrite(10, GPIO.LOW)

def reverse():
   GPIO.digitalWrite(18, GPIO.LOW)
   GPIO.digitalWrite(10, GPIO.HIGH)

def right():
   GPIO.digitalWrite(27, GPIO.HIGH)
   GPIO.digitalWrite(25, GPIO.LOW)

def left():
   GPIO.digitalWrite(27, GPIO.LOW)
   GPIO.digitalWrite(25, GPIO.HIGH)

def strop():
   GPIO.digitalWrite(18, GPIO.LOW)
   GPIO.digitalWrite(10, GPIO.LOW)
   GPIO.digitalWrite(27, GPIO.LOW)
   GPIO.digitalWrite(25, GPIO.LOW)

@webiopi.macro
def ButtonForward():
   forward()

@webiopi.macro
def ButtonReverse():
   reverse()

@webiopi.macro
def ButtonTrunLeft():
   left()

@webiopi.macro
def ButtonTrunRight():
   right()
@webiopi.macro
def ButtonStop():
   stop()
def main():
    try:
     print(__doc__)
     GPIO.digitalWrite(4, GPIO.HIGH)
     GPIO.digitalWrite(17, GPIO.HIGH)
     server = webiopi.Server(port=80)
     server.addMacro(ButtonForward)
     server.addMacro(ButtonReverse)
     server.addMacro(ButtonTrunLeft)
     server.addMacro(ButtonTrunRight)
     server.addMacro(ButtonStop)
     cam = SimpleCV.Camera()
     background = cam.getImage()
     print("Tespite Baslaniyor")
     while True:
        try:
           background = cam.getImage()
           time.sleep(0.1)
           img = cam.getImage()
           to_show = img
           to_show.save("../../..//usr/share/webiopi/htdocs/aaa.jpg")
           dist = ((img - background) + (background - img)).dilate(6)   
        except(KeyboardInterrupt, SystemExit):
           del cam
           server.stop()

它给了我这个错误，即使我没有第 86 行

文件 "tespit.py"，第 86 行 ^ IndentationError：意外的缩进请帮助我，我无法解决问题...

Answer 1

您有两个 try 语句，只有一个 except 语句。

在main函数的末尾为第一个try添加一个except子句，缩进4个空格，就可以了。

第 86 行刚刚结束您的代码，Python 正在寻找匹配的 except。

Answer 2

每个 try 必须至少有一个匹配 except。并且您应该在停止 Webiopi 服务器之前清理 GPIO。
