Python Code (Note some formatting may be lost)
from time import sleep
import RPi.GPIO as gpio

direction_pin = 20
pulse_pin = 21
cw_direction = 0
ccw_direction = 1

gpio.setmode(gpio.BCM)
gpio.setup(direction_pin, gpio.OUT)
gpio.setup(pulse_pin, gpio.OUT)
gpio.output(direction_pin,cw_direction)

try:
while True:
print('Direction CW')
sleep(.5)
gpio.output(direction_pin,cw_direction)
for x in range(200):

except KeyboardInterrupt:
gpio.cleanup()
