url = 'http://www.twitter.com'

sids = []

posts = vkapi.newsfeed.search(q=url)
for item in posts['items']:
    sids.append(item['owner_id'])

for pk in sids:
    if pk >= 1:
        print(vkapi.users.get(user_id=pk))
        time.sleep(.3)
    else:
        print(vkapi.groups.getById(group_id=abs(pk)))
        time.sleep(.3)
