Can' solve the error in raspberry pi : i'm new to raspberry pi and wrote a simple led blink program:
        import RPi.GPIO as GPIO
        import time
        GPIO.setwarnings(False)
        GPIO,setmode(GPIO.BOARD)
        GPIO.setup(3,GPIO.OUT)
        while True:
           GPIO,output(3,1)
           time.sleep(1)
           GPIO.output(3,0)
           time.sleep(1)



but when i run it i get this:
Traceback (most recent call last):
  File "/home/pi/ledblink.py", line 6, in <module>
    GPIO,setmode(GPIO.BCM)
NameError: name 'setmode' is not defined

can anyone help please?
