Can you show the code you use?
You have something below which looks like code, but it doesn't seem to
be Python. It has line numbers. Can you explain what it is please?

The documentation for the telnetlib module includes this example:
>>> from telnetlib import Telnet
>>> tn = Telnet('www.python.org', 79) # connect to finger port
>>> tn.write(b'guido\r\n')
>>> print(tn.read_all())
Login Name TTY Idle When Where
guido Guido van Rossum pts/2 <Dec 2 11:10>
snag.cnri.reston..
I tried running that example, but www.python.org doesn't respond for me
and I eventually got this error:
TimeoutError: [Errno 110] Connection timed out
Maybe my firewall blocks that port, or maybe the site is not listening.
But the important part is the tn.read_all() function. If that works for
you, you can do this instead:
output = tn.read_all()
# display to screen
print(output)
# write to a file
with open("MyFile.txt", "wb") as f:
f.write(output)
# Check that the file wrote correctly.
with open("MyFile.txt", "rb") as f:
print(f.read())
Does that help?
If you need more help, please show your code, without line numbers, and
show any errors you get.
