Not installer yet, so in order to use it, you'll have to copy the alexa.py file to your Python lib search path.
Usage:
from alexa import Alexa
ranker = Alexa() # this might take a while as the rankings are downloaded
google_rank = ranker.getrank('www.google.com')
some_rank = ranker.getrank('www.somestupiddomain.com') # should return -1
