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.
