The donecal package makes it easy to use the restful HTTP API on http://donecal.com/
All you need is your guid which you can pick up on http://donecal.com/help/API once you have created an account.
Install the package with pip or easy_install. Like this:
pip install python-donecal
The API is working swimingly but it's not very rich at the moment. Here's some sample code to get you started:
>>> import datetime
>>> from donecal import DoneCal
>>> dc = DoneCal('XXXXXX-XXXX-XXXX-XXXX-XXXXXX')
>>> data = dc.get_events(datetime.date(2010, 10, 1),
>>> print data['tags']
>>> from pprint import pprint
'end': datetime.datetime(2010, 10, 20, 0, 0),
'start': datetime.datetime(2010, 10, 20, 0, 0),
'title': "Testing stuff on @ProjectX"}
>>> # Now to post something
>>> event, created = dc.add_event("Testing more stuff",
... date=datetime.datetime(2010, 11, 1))
>>> print "Created?", created and "yes" or "no"
· At the moment there are rate limitations but there might be some time in the future to ensure fair access for everyone.
