[Tip] How to get people who does not follow you on twitter

[Bruno Rocha]

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.

Don't you think some components using this on web2py.com home page
would be nice?

Do you mean showing who follows @web2py?

I think it is a good idea, even to create some kind of web2pyers network based on twitter.
