    Hello everyone,i have a problem:I can't connect via python script to switch,using telnetlib module:

    Script:

     

     

     

    import getpass
import telnetlib

HOST = "10.255.23.10"
user = input("Enter your account: ")
password = getpass.getpass()

tn = telnetlib.Telnet(HOST)

tn.read_until(b"Username: ")
tn.write(user.encode('ascii') + b"
    ")
if password:
    tn.read_until(b"Password: ")
    tn.write(password.encode('ascii') + b"
    ")

tn.write(b"show version
    ")

print(tn.read_all().decode('ascii'))

     

     

     

     

    And what's happening:
    python.JPG
    After input password nothing happened.
    I don't know why.
