Best way to store a large python dictionary in a file

Question

I have a python script (script 1) which generate a large python dictionary. This dictionary has to be read by an another script (script 2). Could any one suggest me the best way to write the python dictionary generated by script 1 and to be read by script 2. In past I have used cPickle to write and read such large dictionaries. Is there a beter way to do this?

Answer 1

shelve will give you access to each item separately, instead of requiring you to serialize and deserialize the entire dictionary each time.
