#小练习 pickle模块_分别存储python对象 分类： python Module 2013-09-05 18:07 379人阅读 评论(0) 收藏

如果使用pickle.dump()方法分别存储n个python对象，则读取时也需要n个pickle.load(file)的方法，才能将python对象全部读取出来。

import pickle as p,pprint

shoplistfile =r'G:\data.pkl'

#objects

shoplist = ['apple','mango','carrot']

shoptuple = ('fish',1,'chicken',2)

f = open(shoplistfile,'wb')

#存储对象 分别存储python对象

p.dump(shoplist,f)

p.dump(shoptuple,f,-1)

f.close()

#remove the object

##del shoplist

#读取对象 分别读取python对象

f = open(shoplistfile,'r')

data1 = p.load(f)

pprint.pprint(data1)

data2 = p.load(f)

print data2
