delete uploadcare files older than 14 days

delete.py

#!/bin/python

# installation:
# pip install pytz pyuploadcare==1.3.1

import pytz
from datetime import timedelta, datetime

from pyuploadcare import conf
from pyuploadcare.api_resources import FileList


MAX_LIFETIME = 14  # days
conf.pub_key = 'demopublickey'
conf.secret = 'demoprivatekey'


dt_cutoff = datetime.now(pytz.utc) - timedelta(days=MAX_LIFETIME)


if __name__ == '__main__':

    for f in FileList(stored=True, request_limit=500, until=dt_cutoff):
        print 'deleting {0}...'.format(f.uuid)
        f.delete()

this needs to be updated for batch delete
