copied!<p>You can't avoid serialization if there is no shared memory. There are only bytes on the wire. You could use a library that hides it from you e.g., with <a href="http://codespeak.net/execnet/" rel="nofollow"><code>execnet</code></a> module:</p> <pre><code>#!/usr/bin/env python import execnet gw = execnet.makegateway("ssh=user@host") channel = gw.remote_exec(""" import dbus, sys bus = dbus.SystemBus() remote_object = bus.get_object('daemon.location', '/daemon') controller = dbus.Interface(remote_object, 'daemon.path') channel.send(controller.getValue()) """) tuple_ = channel.receive() print tuple_ print tuple_[0] </code></pre> <p>But it easy to parse simple tuple values yourself using <a href="http://docs.python.org/dev/library/ast#ast.literal_eval" rel="nofollow"><code>ast.literal_eval()</code></a> from stdlib:</p> <pre><code>#fabfile.py import ast from fabric.api import run def getcontroller(): """Return controller value.""" cmd = """ import dbus, sys bus = dbus.SystemBus() remote_object = bus.get_object('daemon.location', '/daemon') controller = dbus.Interface(remote_object, 'daemon.path') print repr(controller.getValue()) """ #NOTE: you must escape all quotation marks output = run('python -c "%s"' % cmd) tuple_ = ast.literal_eval(output) print tuple_[0] </code></pre> <p>Example: <code>$ fab getcontroller -H user@host</code></p> <p>Here I've used <a href="http://fabfile.org" rel="nofollow"><code>fabric</code></a> to run the command on remote host.</p> <p>You could use JSON as a serialization format if the other end doesn't produce Python literals:</p> <pre><code>>>> import json >>> t = (1, "a") >>> json.dumps(t) '[1, "a"]' >>> json.loads(_) [1, u'a'] >>> </code></pre>
