Python does not come with an SSH library, which one are you using?
I am guessing you are using pxssh but it is better for you to 
explicitly let us know any third party module and the operating
system. 

The example they provide on the site[0] says you need to use the 
following to get the output.

""""
s.sendline ('uptime')  # run a command
s.prompt()             # match the prompt
print s.before         # print everything before the prompt.
""""
