Blink script gives me "name error 'BCM' is not defined"

Question

I recently purchased a Raspberry Pi 2 and I am trying to run a simple a simple Blink program but getting this error:

name error 'BCM' is not defined

This is my script

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO,BCM)
GPIO.setwarnings(False)

led = 7

while True:
    GPIO.output(led,1)
    time.sleep(2)
    GPIO.output(led,0)

Answer 1

It's GPIO.BCM you want. Dot rather than comma.

GPIO.setmode(GPIO.BCM)
