Maybe it can be usefull for someone building a twitter app with web2py,
I take this form an example posted by @gwidion on twitter.
<code>
# -*- coding: utf-8 -*-
import urllib, json
# Author: João S. O. Bueno
# License: LGPL V 3.0
def get_people_set(method, id, update=None):
url = "http://api.twitter.com/1/statuses/%s/%s.json"; % (method, id)
people = set()
cursor = "-1"
while True:
data = json.loads(urllib.urlopen(url + "?cursor=%s" %
cursor).read())
cursor = data["next_cursor"]
if update:
update(cursor)
these_people = set(person["screen_name"] for person in
data["users"])
people.update(these_people)
if not cursor or not these_people :
break
return people
</code>
As it returns a set, it is easy to get its intersection/union and rest.
<code>
friends = get_people_set("friends", id, self.status)
followers = get_people_set("followers", id, self.status)
</code>
To get who does not follow you, simple do:
<code>
noFollowers = sorted(friends - followers)
</code>
I am building my own twitter client, using @michelecomitini example,
including some more options as this one.
