I need to save to disk a little dict
object whose keys are of the type str
and values are int
s and then recover it. Something like this:
{'juanjo': 2, 'pedro':99, 'other': 333}
What is the best option and why? Serialize it with pickle
or with simplejson
?
I am using Python 2.6.
I prefer JSON over pickle for my serialization. Unpickling can run arbitrary code, and using pickle
to transfer data between programs or store data between sessions is a security hole. JSON does not introduce a security hole and is standardized, so the data can be accessed by programs in different languages if you ever need to.
