Column Families are keyed attribute/value pairs, your 'girls' column
will need to be serialised on save, and deserialiased on load so that
it can treated as your intended array. Pickle will do this for you
(http://docs.python.org/library/pickle.html)
eg:
import pycassa
import pickle
client = pycassa.connect()
cf = pycassa.ColumnFamily(client, 'mygame', 'user')
key = '1234567890'
value = {
'name': 'Lee Li',
'age'; '21',
'girls': pickle.dumps(['java', 'actionscript', 'python'])
}
cf.insert(key, value)
hope that helps
