B4J Question Raspberry PI - how to write my python code?

[IamTrying]

I have Raspberry PI 3 Model B board.

Where i am using BASH, Python. How do i write the following code in B4J for Raspberry board and replace the Python code.

###### On boot - setup following and run my Python #######
$ cat /etc/rc.local
#!/bin/sh -e

# Test if rc.local even executing?
echo 'hello world works?' > /tmp/test

# Setup the GPIP
echo "18" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio18/direction
echo "1" > /sys/class/gpio/gpio18/value
echo "4" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio4/direction
echo "1" > /sys/class/gpio/gpio4/value

# Python infinite loop run
# with ERROR handler
/home/pi/pypy.py > /var/log/pypy.py.log 2>&1 &

exit 0

How to B4J the following Python code for RPI?

$ chmod +x /home/pi/pypy.py
$ cat /home/pi/pypy.py
#!/usr/bin/python

import urllib2
import os
import time
from time import sleep

while True:
  time.sleep(2)

  try:
   contents = urllib2.urlopen("https://www.b4x.com/commands").read()
   if contents in ('reboot', 'reboots'):
     os.system('echo "0" > /sys/class/gpio/gpio4/value')
     os.system('echo "0" > /sys/class/gpio/gpio18/value')
     sleep(0.5)
     os.system('echo "1" > /sys/class/gpio/gpio4/value')
     os.system('echo "1" > /sys/class/gpio/gpio18/value')

  except:
   print "ERROR - so what continue?"
