A Twitter Python web service

Taking the code from the previous post: here is a Python web service that reads the Twitter feed for a given query and returns a subset of the results in JSON:

import urllib
import json
import string
import SimpleXMLRPCServer
from SimpleXMLRPCServer import SimpleXMLRPCServer
from SimpleXMLRPCServer import SimpleXMLRPCRequestHandler

def runQuery(query, pp, pages):
 p = urllib.urlopen('http://search.twitter.com/search.json?q=' + query + '&rpp=' + str(pp) + '&page=' + str(pages))
 s = json.load(p)
 dic = json.dumps(s)
 dic = string.replace(dic, 'null', '"none"')
 dx = eval(dic)
 listOfResults = dx['results']
 ret = []
 for result in listOfResults:
  ret.append( { 'id':result['id'], 'from_user':result['from_user'], 'created_at':result['created_at'], 'text': result['text'] } )
 completeRet = {"results": json.dumps(str(ret))}
 return str(completeRet)
  
class RequestHandler(SimpleXMLRPCRequestHandler):
 rpc_paths=('/RPC2')
 
server=SimpleXMLRPCServer(("localhost", 8000), requestHandler=RequestHandler)
server.register_introspection_functions()
server.register_function(runQuery, 'qry')
server.serve_forever()

More potential uses of this (including Google Apps, Mongo, or Processing) later. And here is how to use it (from Python):

>>> import xmlrpclib
>>> s = xmlrpclib.ServerProxy('http://localhost:8000')
>>> print s.qry('Bumrungrad', 10, 1)

Where the first numeric parameter is the number of records per page and the second, the number of page (max 100/15).
