An unofficial web scraper for Yahoo! Fantasy Football (YFF) data. Not affiliated with or endorsed by Yahoo! in any way.
Should be as simple as pip install yahoofantasyfootball. Alternately, python setup.py install.
In addition to the libraries listed in requirements.txt, this library relies upon the presence of PhantomJS. Get it, install it, love it.
import yahoofantasyfootball
LEAGUE_URL = 'http://football.fantasysports.yahoo.com/f1/123456'
YAHOO_USERNAME = 'foo'
YAHOO_PASSWORD = 'bar' # please be careful not to publish your password
yff = yahoofantasyfootball.YahooFantasyFootball(LEAGUE_URL, YAHOO_USERNAME, YAHOO_PASSWORD)
yff.refresh() # logs in if necessary, pulls down league HTML, processes it
print yff.scores, yff.standings, yff.matchups

This library relies upon screen scraping, which is an inherently unreliable technique. YFF has held its templates relatively steady between the 2013-2014 and 2014-2015 seasons, but that could change at any moment. They should really consider making a non-terrible API.

I have no idea if Yahoo! supports non-ASCII team names, but if they do, they will probably not be collected correctly, as I am stripping out Unicode to get rid of the silly trophy icons they put next to team names.
-
Projected scores seem to not be reliably available through the week (it is possible they have been removed permanently from the relevant HTML table). Please be sure to test if the value is None before using that field.
-
There is a frightening amount of additional data available through the YFF interface. Pull requests are welcome! However, it is unlikely that YFF is legally able to relay scores or player information to third parties. Consequently I am unlikely to accept PRs that collect individual player stats or other information that the NFL might have IP rights to. User-generated content and game outcome data is all fair game, though, I think.
