I'm not being able to access some GData Contacts properties, such as gender

Here's the code:

def fetch_feed(self):
        client = gdata.contacts.service.ContactsService()
        client.ClientLogin(username, password) #Will change to AuthSub later.
        query = gdata.contacts.service.ContactsQuery()
        query.max_results = 3000
        feed = client.GetContactsFeed(query.ToUri())
        memcache.set('feed',feed, 3600)
        return feed

feed = self.fetch_feed()
self.PrintFeed(feed)

def PrintFeed(self, feed):
        for entry in feed.entry:
            print entry.* #example... i can access properties such as entry.title, entry.id, entry.updated, but can't access a whole lot more.

What am i doing wrong, or what am i not doing at all? I posted the same question on the Apps API forum, just to clarify things.

EDIT Here's what i'm importing:

from google.appengine.api import memcache, users
from google.appengine.ext import db, webapp
from google.appengine.ext.webapp import util
import atom
import atom.url
import datetime
import gdata.alt.appe开发者_如何学Pythonngine

import gdata.contacts
import gdata.contacts.client
import gdata.contacts.data
import gdata.contacts.service
import gdata.client
import gdata.service
import settings

EDIT2: The error i got after fixing the qry typo:

You can try the V3 client

client = gdata.contacts.client.ContactsClient()
client.client_login(usr, passwd, "myscript")
qry = gdata.contacts.client.ContactsQuery(max_results=3000)
feed = client.get_contacts(query=qry)

for entry in feed.entry:
    # do something with entry
