將對象序列化（保存的意思）和反序列化（讀取的意思）

cpickle是pickle的C語言編譯版本

下面是dump和load的用法

import pickle ?
favorite_color = { "lion": "yellow", "kitty": "red" } ?
pickle.dump( favorite_color, open( "save.p", "wb" ) ) ?


import pickle ?
favorite_color = pickle.load( open( "save.p", "rb" ) ) ?
print"favorite_color=",favorite_color

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

下面是dumps和loads的用法：

import cPickle as pickle
origin = ('this is a string', 42, [1, 2, 3], None)


print origin
print"##########################################################################################"
p1 = pickle.dumps(origin)
print "p1=",p1


t1 = pickle.loads(p1)
print"t1=",t1


print"##########################################################################################"
p2 = pickle.dumps(origin, True)
print p2
t2 = pickle.loads(p2)
print"t2=",t2

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

涉及文件的序列化與反序列化

import cPickle


data = range(1000)


cPickle.dump(data,open("./data.pkl","wb"))?




data = cPickle.load(open("./data.pkl","rb"))


print"data=",data
print"#######################################################"
data_string = cPickle.dumps(data)


data = cPickle.loads(data_string)
print"data=",data

總結：

dumps和loads是處理字符串的

dump和load是涉及到處理字符串并且與文件進行交互的。
