Raspberry pi：我使用一些代码进行电子邮件警报，使用GPIO端口进行LED通知

Question

Im using Python the RPi, and found some coding online that would notify me of emails that come in and light up an LED on the GPIO ports

Here is the code:

#!/usr/bin/env python

import RPi.GPIO as GPIO, feedparser, time

DEBUG = 1

USERNAME = ""
PASSWORD = ""

NEWMAIL_OFFSET = 1
MAIL_CHECK_FREQ = 60

GPIO.setmode(GPIO.BCM)
GREEN_LED = 18
RED_LED = 23
GPIO.setup (GREEN_LED, GPIO.OUT)
GPIO.setup(RED_LED, GPIO.OUT)

while True:

    newmails = int(feedparser.parse("https://" + USERNAME + ":" + PASSWORD +"@mail.google.com/gmail/feed/atom")["feed"]["fullcount"])

    if DEBUG:
        print "You have" newmails, "new emails!"

        if newmails > NEWMAIL_OFFSET:
            GPIO.output (GREEN_LED, True)
            GPIO.output (RED_LED, False)

        else:

            GPIO.output(GREEN_LED, False)
            GPIO.output(RED_LED, True)

        time.sleep(MAIL_CHECK_FREQ)


except KeyboardInterrupt:
    GPIO.cleanup()

And Python says that the " by the first print is invalid. Anyone know why?

Answer 1

Is this an exact copy-paste from the code on your machine? It looks like you're missing a comma after "You have" and before newmails .
