Question

曾经遇到我的一个脚本问题。运行脚本时，在第23行下出现以下消息：

SyntaxError：缩进中的制表符和空格使用不一致

我尝试使用Anaconda将任何制表符替换为4/8空格，但没有成功。

有什么主意我要去哪里吗？

干杯。

import RPi.GPIO as GPIO
import time

sensor = 4

GPIO.setmode(GPIO.BCM)
GPIO.setup(sensor, GPIO.IN, GPIO.PUD_DOWN)

previous_state = False
current_state = False

try:

    while True:
        time.sleep(0.1)
        previous_state = current_state
        current_state = GPIO.input(sensor)
        if current_state != previous_state:
            new_state = "HIGH" if current_state else "LOW"
            print("GPIO pin %s is %s" % (sensor, new_state))
            import smtplib

        smtpUser = 'rpigroupproject@gmail.com'
        smtpPass = 'W1r3l355'

        toAdd = 'rpigroupproject@gmail.com'
        fromAdd = smtpUser

        subject = 'ALERT!'
        header = 'To: ' + toAdd + '\n' + 'From: ' + \
            fromAdd + '\n' + 'Subject:' + subject
        body = 'Motion was detected...'

        print header + '\n' + body

        s = smtplib.SMTP('smtp.gmail.com', 587)

        s.ehlo()
        s.starttls()
        s.ehlo()

        s.login(smtpUser, smtpPass)
        s.sendmail(fromAdd, toAdd, header + '\n' + body)

        s.quit()

except:
    GPIO.cleanup()

此处缩进固定。您应该配置编辑器，以免再次出现此错误。

import RPi.GPIO as GPIO
import time

sensor = 4

GPIO.setmode(GPIO.BCM)
GPIO.setup(sensor, GPIO.IN, GPIO.PUD_DOWN)

previous_state = False
current_state = False

try:

    while True:
        time.sleep(0.1)
        previous_state = current_state
        current_state = GPIO.input(sensor)
        if current_state != previous_state:
            new_state = "HIGH" if current_state else "LOW"
            print("GPIO pin %s is %s" % (sensor, new_state))
            import smtplib

    smtpUser = 'rpigroupproject@gmail.com'
    smtpPass = 'W1r3l355'

    toAdd = 'rpigroupproject@gmail.com'
    fromAdd = smtpUser

    subject = 'ALERT!'
    header = 'To: ' + toAdd + '\n' + 'From: ' + fromAdd + '\n' + 'Subject:' + subject
    body = 'Motion was detected...'

    print header + '\n' + body

    s = smtplib.SMTP('smtp.gmail.com',587)

    s.ehlo()
    s.starttls()
    s.ehlo()

    s.login(smtpUser, smtpPass)
    s.sendmail(fromAdd, toAdd, header + '\n' + body)

    s.quit() 

except:
   GPIO.cleanup()

Answer 2

我不确定您是否使用自定义标识，但只是出于测试目的，我建议您重置所有自定义并使用 tabs 。

例如，这是您的以下代码示例。您会看到 try-while 和 while 之后的标识不一致

try:
   while True:
    time.sleep(0.1)
    previous_state = current_state
    current_state = GPIO.input(sensor)

具有一致标识的外观如下：

try:
    while True:
        time.sleep(0.1)
        previous_state = current_state
        current_state = GPIO.input(sensor)

Python语法错误，找不到缩进的解决方案
