Python. Сериализация объектов.

import pickle

def serialize(output, obj):
    file = open(output, 'wb')
    pickle.dump(obj, file)
    file.close()

def unserialize(output):
    file = open(output, 'rb')
    obj = pickle.load(file)
    file.close()

    return obj

obj = ['a', 'b', 'c']
output = 'dump.txt'
serialize(output, obj)

obj = unserialize(output)
