一 pickle包

1 将内存中的对象转换成为文本流：

import pickle

class Bird(object):
    have_feather = True
    way_of_reproduction  = 'egg'
 
summer = Bird()
pickleString = pickle.dumps(summer) # serialize object

import pickle

class Bird(object):
    have_feather = True
    way_of_reproduction  = 'egg'
 
summer = Bird()
fileName = 'save.pkl'
with open(fileName, 'w') as f: # open file with write-mode
    pickleString = pickle.dump(summer, f) # serialize and save object

2 重建对象

import pickle
 
# define the class before unpickle
class Bird(object):
    have_feather = True
    way_of_reproduction  = 'egg'
 
fileName = 'save.pkl'
with open(fileName, 'r') as f:
    summer = pickle.load(f) # read file and build object

二 cPickle包

import cPickle as pickle
