Pickle is more for storing complex objects (arrays, dict, etc). pickling a string makes it bigger.
I have stored large text chunks in text and/or blob columns compressed with gzip.zlib.compress and extracted with gzip.zlib.decompress Comparison: import cPickle as Pickle import gzip x = "asdfasdfasdfasdfasdfasdfasdfasdfasdf" print len(x) >> 36 print len(Pickle.dumps(x)) >> 44 print len(gzip.zlib.compress(x)) >> 14 Vince On Wed, Jun 24, 2009 at 11:17 AM, Dinesh B Vadhia <dineshbvad...@hotmail.com > wrote: > I want to pickle (very long) strings and save them in a sqlite db.
