Raspberry PI: 2 кнопки, 2 светодиода ⇐ Python

[Anonymous]

Я пытаюсь создать программу на Python с Raspberry Pi, в которой при нажатии кнопки загорается только красный светодиод, а когда я нажимаю другую кнопку, загорается только зеленый светодиод. Если ни одна кнопка не нажата, все светодиоды выключены. Но когда я пытаюсь его запустить, оба светодиода горят, а когда я нажимаю кнопку, монитор говорит, что я ее нажал, но ничего не меняется. Что я могу сделать, чтобы это исправить? Я на 100% уверен, что проблем с проводкой нет, и монитор не показывает ошибок. Кстати, вот код:

import RPi.GPIO as GPIO
