You cannot just type telnet commands into Python you need to use
the telnet API. (Type help(telnetlib) at the >>> prompt or visit the
modules documentation page)

A typical session might look something like:

>>> import telnetlib
>>> tn = telnetlib.Telnet('myhost.com')
>>> response = tn.read()
>>> print(response)
..... some stuff here ....
>>> tn.close()

That's assuming you have telnet access to myhost.com of course, many sites
don't allow it because of the security issues associated with telnet.
ssh is
probably a better bet.

But in either case don't expect a telnet interactive session - that's
what the
telnet command (or ssh) is for. Python gives you the ability to automate a
session, with no human interactivity required. If you want to interact
you'll
need to read the output and check for prompts from the host then relay
those prompts to your user from Python.
