Original at https://github.com/bitly/bitly-api-python seems abandoned. I tried to aggregate the good pull-requests in this repo.
pip install git+git://github.com/jimmy927/bitly-api-python
import bitly_api
c = bitly_api.Connection('bitlyapidemo','R_{{apikey}}')
# or to use oauth2 endpoints
c = bitly_api.Connection(access_token='...')
c.shorten('http://www.google.com/')
Your username is the lowercase name shown when you login to bitly, your access token can be fetched using the following ( http://dev.bitly.com/authentication.html ):
curl -u "username:password" -X POST "https://api-ssl.bitly.com/oauth/access_token"
To run the tests either export the environment variable or set it up inline before calling nosetests:
bitly-api-python $ BITLY_ACCESS_TOKEN=<accesstoken> nosetests
