I am new one for python trying to take telnet from my windows7 pc to another windows PC using below script. 


import telnetlib
import os

host_ip = "10.22.7.3"
user = "user"
password = "user"
tnet_hndl = telnetlib.Telnet(host_ip)
print (tnet_hndl.read_until(b"login: "))
tnet_hndl.write(user.encode('ascii') + b"\r\n")
print (tnet_hndl.read_until(b"password: "))
tnet_hndl.write(password.encode('ascii') + b"\r\n")
print (tnet_hndl.read_until(b"# "))
tnet_hndl.write(b"" + b"\r\n")
print (tnet_hndl.read_until(b"# "))
