Python---序列化的模块pickle（标准模块）

Python3

python2与python3保存的pickle文件不兼容问题

# -*- coding:utf-8 -*-
try:
    import cPickle as pickle
except ImportError:
    import pickle

cookies_file = "{0}.cookies".format("liudon")
with open(cookies_file, 'wb') as f:
    pickle.dump({"name": "liu"}, f, protocol=2)
with open(cookies_file, 'rb') as f:
    cookies = pickle.load(f)
print cookies      # 结果：{'name': 'liu'}

pickle.dump({"name": "liu"}, open(cookies_file, 'wb'), protocol=2)
cookies = pickle.load(open(cookies_file, 'rb'))
print cookies      # 结果：{'name': 'liu'}

try:
    import cPickle as pickle
except ImportError:
    import pickle

# 在python3中序列化Python2不能识别，这时只要在python3中这样序列化：
with open('data.pkl', 'wb') as f:
    pickle.dump(message, f, protocol=2)

# 这样序列化后的message在Python2里面就能读取
with open('data.pkl', 'rb') as f:
    samples, labels = pickle.load(f)
