Twython

Twython is library providing an easy (and up-to-date) way to access Twitter data in Python

Features

• Query data for:
  • User information
  • Twitter lists
  • Timelines
  • Direct Messages
  • and anything found in the docs
• Image Uploading!
  • Update user status with an image
  • Change user avatar
  • Change user background image
  • Change user banner image

Installation

(pip install | easy_install) twython

... or, you can clone the repo and install it the old fashioned way

git clone git://github.com/ryanmcgrath/twython.git
cd twython
sudo python setup.py install

Usage

Authorization URL

from twython import Twython

t = Twython(app_key, app_secret)

auth_props = t.get_authentication_tokens(callback_url='http://google.com')

oauth_token = auth_props['oauth_token']
oauth_token_secret = auth_props['oauth_token_secret']

print 'Connect to Twitter via: %s' % auth_props['auth_url']

Be sure you have a URL set up to handle the callback after the user has allowed your app to access their data, the callback can be used for storing their final OAuth Token and OAuth Token Secret in a database for use at a later date.

Handling the callback

from twython import Twython

# oauth_token_secret comes from the previous step
# if needed, store that in a session variable or something.
# oauth_verifier and oauth_token from the previous call is now REQUIRED # to pass to get_authorized_tokens

# In Django, to get the oauth_verifier and oauth_token from the callback
# url querystring, you might do something like this:
# oauth_token = request.GET.get('oauth_token')
# oauth_verifier = request.GET.get('oauth_verifier')

t = Twython(app_key, app_secret,
            oauth_token, oauth_token_secret)

auth_tokens = t.get_authorized_tokens(oauth_verifier)
print auth_tokens

Function definitions (i.e. get_home_timeline()) can be found by reading over twython/endpoints.py

Getting a user home timeline

from twython import Twython

# oauth_token and oauth_token_secret are the final tokens produced
# from the 'Handling the callback' step

t = Twython(app_key, app_secret,
            oauth_token, oauth_token_secret)

# Returns an dict of the user home timeline
print t.get_home_timeline()

Catching exceptions

Twython offers three Exceptions currently: TwythonError, TwythonAuthError and TwythonRateLimitError

from twython import Twython, TwythonAuthError

t = Twython(MY_WRONG_APP_KEY, MY_WRONG_APP_SECRET,
            BAD_OAUTH_TOKEN, BAD_OAUTH_TOKEN_SECRET)

try:
    t.verify_credentials()
except TwythonAuthError as e:
    print e

Streaming API

from twython import TwythonStreamer


class MyStreamer(TwythonStreamer):
    def on_success(self, data):
        print data

    def on_error(self, status_code, data):
        print status_code, data

# Requires Authentication as of Twitter API v1.1
stream = MyStreamer(APP_KEY, APP_SECRET,
                    OAUTH_TOKEN, OAUTH_TOKEN_SECRET)

stream.statuses.filter(track='twitter')

Notes

Twython (as of 2.7.0) is currently in the process of ONLY supporting Twitter v1.1 endpoints and deprecating all v1 endpoints! Please see the Twitter v1.1 API Documentation to help migrate your API calls!

Development of Twython (specifically, 1.3)

As of version 1.3, Twython has been extensively overhauled. Most API endpoint definitions are stored in a separate Python file, and the class itself catches calls to methods that match up in said table.

Certain functions require a bit more legwork, and get to stay in the main file, but for the most part it's all abstracted out.

As of Twython 1.3, the syntax has changed a bit as well. Instead of Twython.core, there's a main Twython class to import and use. If you need to catch exceptions, import those from twython as well.

Arguments to functions are now exact keyword matches for the Twitter API documentation - that means that whatever query parameter arguments you read on Twitter's documentation (http://dev.twitter.com/doc) gets mapped as a named argument to any Twitter function.

For example: the search API looks for arguments under the name "q", so you pass q="query_here" to search().

Doing this allows us to be incredibly flexible in querying the Twitter API, so changes to the API aren't held up from you using them by this library.

Twython 3k

Full compatiabilty with Python 3 is now available seamlessly in the main Twython package. The Twython 3k package has been removed as of Twython 2.8.0

Questions, Comments, etc?

My hope is that Twython is so simple that you'd never have to ask any questions, but if you feel the need to contact me for this (or other) reasons, you can hit me up at ryan@venodesigns.net.

Want to help?

Twython is useful, but ultimately only as useful as the people using it (say that ten times fast!). If you'd like to help, write example code, contribute patches, document things on the wiki, tweet about it. Your help is always appreciated!
