Why not use python pickle?
Python has a great serializing module called pickle it is very easy to use.
import cPickle
cPickle.dump(obj, open('save.p', 'wb'))
obj = cPickle.load(open('save.p', 'rb'))
There are two disadvantages with pickle:
- It’s not secure against erroneous or
maliciously constructed data. Never
unpickle data received from an
untrusted or unauthenticated source. - The format is not human readable.
If you are using python 2.6 there is a builtin module called json. It is as easy as pickle to use:
import json
encoded = json.dumps(obj)
obj = json.loads(encoded)
Json format is human readable and is very similar to the dictionary string representation in python. And doesn’t have any security issues like pickle. But might be slower than cPickle.
