代码调试，为什么操作后LED灯不会熄灭？

Question

I wroted a code, whitch turns on leds by the date and color from the txt file. If the date is correct leds turns on, but when correct time passes leds wont turn off, they still glowing until next date. So, why leds won't turn off, where is the problem? Please help, I have tried almost everything.

import sys
import time
import datetime
import RPi.GPIO as GPIO
import SDL_DS1307

GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)



LED_R = 17
LED_G = 27
LED_B = 22


GPIO.setup(17, GPIO.OUT)
GPIO.setup(27, GPIO.OUT)
GPIO.setup(22, GPIO.OUT)


filename = time.strftime("%Y-%m-%d%H:%M:%SRTCTest") + ".txt"
starttime = datetime.datetime.utcnow()

ds1307 = SDL_DS1307.SDL_DS1307(1, 0x68)
ds1307.write_now()

while True:
    currenttime = datetime.datetime.utcnow()
    deltatime = currenttime - starttime
    data=time.strftime("%Y"+"%m"+"%d"+"%H"+"%M")
    with open('data.txt') as f:
            for line in f:
                    parts=line.split()                               
                    if parts[0]<=(data)<=parts[1]:
                            if parts[2]=='raudona':
                                    GPIO.putput(LED_R, False)
                                    GPIO.putput(LED_G, True)
                                    GPIO.putput(LED_B, True)

                                    GPIO.putput(LED_R, False)
                                    GPIO.putput(LED_G, True)

                                    GPIO.putput(LED_B, False)

            time.sleep(10.0)

What a nice opportunity to use the for-else construct .

If an instruction to turn LED lights on is found, turn the LEDs on and then break from the loop, because the task is completed.

For the case, no instruction was found, ie no break was executed, add the else suite to the loop and turn off all LEDs there.

            for line in f:
                parts=line.split()
                if parts[0]<=(data)<=parts[1]:
                    if parts[2]=='raudona':
                        GPIO.putput(LED_R, False)
                        GPIO.putput(LED_G, True)
                        GPIO.putput(LED_B, True)
                        break
                    elif parts[2]=='zalia':
                        GPIO.putput(LED_R, True)
                        GPIO.putput(LED_G, False)
                        GPIO.putput(LED_B, True)
                        break
                    # elif .....
            else:
                 GPIO.putput(LED_R, False)
                 GPIO.putput(LED_G, False)
                 GPIO.putput(LED_B, False)

Hey brother I believe I have found the answer to your problem. Okay here is what you will do. THIS IS A THOROUGH GUIDE ON DEBUGGING A BLINKING LED

Endeavour to go through the guide as it contains useful information on solving the issue that you are experiencing.

You see Raspberry Pi is a very interesting and unique piece of device
