You will still need to worry about escaping because on the remote end
you invoke ssh which is a shell. The obvious call:

subprocess.call(["ssh", "remoteuser@remote", "python", "remote.py", "arg
1", "arg 2", "arg 3"])

won't work because ssh will break up the "arg n" strings. You need to
use  "'arg n'" or put the whole python command in a string like:

"python TEST/testargs.py 'arg 1' 'arg 2' 'arg 3'"
