How to save a show run from a switch?

[raikone14]

I created a code to Connect through a switch using telnet.
It is working, but now I am trying to see the running config and save in a file.
The code is not returning the running config or any error.
Any idea guys? thank you .

That is OP code

import getpass
import telnetlib


host = "10.8.4.100"
user = input("Entre seu usuário")
password = getpass.getpass()


tn = telnetlib.Telnet(host)

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

tn.write(b"sh run\n")
tn.write(b"exit\n")

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

Aside from python, how would you get that info?  If you telnet in, is there a command you can run to get the config?
