Here is an example demonstrating the basic usage of pickle:-
# Importing pickle try: import cPickle as pickle # Python 2 except ImportError: import pickle # Python 3 # Creating Pythonic object: class Family(object): def __init__(self, names): self.sons = names def __str__(self): return ' '.join(self.sons) my_family = Family(['John', 'David']) # Dumping to string pickle_data = pickle.dumps(my_family, pickle.HIGHEST_PROTOCOL) # Dumping to file with open('family.p', 'w') as pickle_file: pickle.dump(families, pickle_file, pickle.HIGHEST_PROTOCOL) # Loading from string my_family = pickle.loads(pickle_data) # Loading from file with open('family.p', 'r') as pickle_file: my_family = pickle.load(pickle_file)
See Pickle for detailed information about Pickle.
WARNING: The official documentation for pickle makes it clear that there are no security guarantees. Don't load any data you don't trust its origin.
