Storing Python dictionaries

by

I’m used to bringing data in and out of Python using CSV files, but there are obvious challenges to this. Are there simple ways to store a dictionary (or sets of dictionaries) in a JSON or pickle file?

For example:

data = {}
data ['key1'] = "keyinfo"
data ['key2'] = "keyinfo2"

I would like to know both how to save this, and then how to load it back in.
