Make telnet communication using python

It is my first question here :D

I have to send some commands from my personal computer (Linux-Red Hat) to a server (Robot Controller). I saw that the controller have a Ethernet protocol that allows sending commands using telnet communication.

My question: is it possible to make telnet connection, send commands and read the output using python? If it is, can you help me?

Thank you.

In python they have telnetlib, which allows telnet communication. I'm pretty sure that this is what you're looking for. You can find the docs at https://docs.python.org/2/library/telnetlib.html Here is a basic way to logon to a windows server and get the directory listing (Courtesy of the docs pages above)

import telnetlib

HOST = "localhost"
user = "username"
password = "password"

tn = telnetlib.Telnet(HOST)

tn.read_until("login: ")
tn.write(user + "\n")
if password:
    tn.read_until("Password: ")
    tn.write(password + "\n")

tn.write("dir\n")
tn.write("exit\n")

print tn.read_all()
