I'm rather surprised that you are using the Python debugger to
experiment with this. I don't think I've seen anyone else do that
before. Normally people just use the interactive shell.

What's sshClient and where did it come from? When I try to import
it, I get this error:

py> import sshClient
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: No module named 'sshClient'


Since you haven't told us what sshClient is, and it's not a
standard part of Python, that makes it a *little* difficult to
tell you what the answer to your problem is.
