Accessing R-PI GPIO using RPi.GPIO module

• How To Use GPIO Pins On Raspberry Pi – Buttons And LED Tutorial This has the correct pinout picture and input example
• Getting Started with Raspberry Pi GPIO and Python dont use the pinout picture. I installed RPi.GPIO as suggested here
• Below python code creates a 10Hz pulse at line 4

And outputs to line 8 what is input at line 7. <python>

import time
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(4, GPIO.OUT)
GPIO.setup(7, GPIO.IN)
GPIO.setup(8, GPIO.OUT)
for x in range(0,1000):
  time.sleep(0.1)
  GPIO.output(4,GPIO.HIGH)
  time.sleep(0.1)
  GPIO.output(4,GPIO.LOW)
  if (GPIO.input(7) == True):
        GPIO.output( 8, GPIO.HIGH)
  else:
        GPIO.output( 8, GPIO.LOW)

</python>
