send 'byteArray' through socket

Hi Greats...

Once again I have a question and am sure will get a quick answer.

I am trying to communicate to another device using socket.
Here is my code :

import socket

data = bytearray(b"hello world")
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect(("192.168.1.2", 5000))
client_socket.send(data)
client_socket.close()

The above code works fine on python, but when I tried to run the same in Sikuli. It displays 'bytearray' not defined error. Is there any alternative to send the info through socket.
The server requires ASCII info. I tried convert it into ascii and send but I wasn't able to.

Thanks for your valuable time and help.

Regards,
Silverallis
