You want two libraries.

First, the low-level paramiko (http://www.lag.net/paramiko/) which 
handles all the basic ssh connection stuff.

Next, fabric (http://docs.fabfile.org/en/1.8/), which layers a very easy 
to use application layer on top of paramiko.  Fabric is most commonly 
used in conjunction with a near command-line driver tool called fab, but 
you can also work directly with the library layer 
(http://docs.fabfile.org/en/1.8/usage/library.html).

Fabric rocks.  Don't waste your time with anything else (but see the 
next paragraph).

As far as I know, fabric only works with ssh.  If you are forced to use 
telnet to talk to legacy equipment, that's another problem.
