xmlrpc is really easy in python.
nop_90 already pointed out how you just create an object and call the xml-rpc methods on the object itself.
to post to a livejournal blog:
import xmlrpclib
import datetime
server = xmlrpclib.ServerProxy("http://www.livejournal.com/interface/xmlrpc")
now = datetime.datetime.now()
# the livejournal xml-rpc reference: http://www.livejournal.com/doc/server/ljp.csp.xml-rpc.postevent.html
# defines the args for the postevent method as a 'struct' which translates to a dictionary in python
args = {"username" : "username",
"password" : "password",
"event" : "They dyed me this color! That's how clever they are!",
"subject" : "I'm thinking with sand here",
"year" : now.year,
"mon" : now.month,
"day" : now.day,
"hour": now.hour,
"min" : now.minute
}
# call the remote method as a method of the server object
response = server.LJ.XMLRPC.postevent(args)
print response
