pytwitter is a python library for the twitter API. It's pretty mimimal and is coded so that the methods are directly translated to the API urls - pytwitter.friendships_exists() will always make a request to http://twitter.com/friendships/exists.xml (or .json). If twitter add or change any methods, the library will instantly be able to use them.

>>> import pytwitter

>>> client = pytwitter.pytwitter(username='user', password='mypass')

>>> client.statuses_update(status='hello interwebs!!')

>>> client.friendships_create(id='buz')
