Passing arguments to & executing, a python script on a remote machine from a python script on local machine

[ashish]

Hi PyTutor Folks

Here is my situation

1. I have two machines. Lets call them local & remote.
Both run ubuntu & both have python installed

2. I have a python script, local.py, running on local which needs to pass arguments ( 3/4 string arguments, containing whitespaces like spaces, etc ) to a python script, remote.py running on remote (the remote machine).

I have the following questions:

1. What's the best way to accomplish my task ?
I have researched quite a bit & so far found really conflicting & complex workarounds. 

I googled & found people using several libraries to accomplish ssh to remote machine & execute a command on remote machine.
paramiko ( now forked into the ssh moduke), fabric, pushy ,etc

People who have used any of these libraries, which one would you recommend, as the most apt (simple & easy to use, lightweight, best performance, etc) for my situation ?

2. I would prefer a solution, which does NOT require the installation of extra libraries on the local & remote machines.
If installing external librar

3. Has anybody been able to do this using os.system ?

I tried this
>>> import os
>>> os.system ("ssh remoteuser at remote python remote.py arg1 arg2 arg3")

This worked, but if the arguments i tried to pass, had spaces, i was not able to 'escape' the spaces.

Any & all explanations/links/code snippets/thoughts/ideas/suggestions/feedback/comments/ of the Python tutor community would be greatly appreciated.

Thanks a ton

cheers
