I'm surprised no one has mentioned pickle.
>>> import pickle
>>> names = {"Candy" : 2.95, "Popcorn" : 4.95}
>>> pickle.dumps(names)
"(dp0\nS'Popcorn'\np1\nF4.9500000000000002\nsS'Candy'\np2\nF2.9500000000000002\ns."
>>> pickle.loads(pickle.dumps(names))
{'Popcorn': 4.9500000000000002, 'Candy': 2.9500000000000002}
