直接上代码吧

#-*-coding:utf-8

import  os

if os.path.exists('d:\\cpickle.data'):
    os.remove('d:\\cpickle.data')


import cPickle as P
shoplist=['apple','banana','pear']
P.dump(shoplist,file('d:\\cpickle.data','w'))
f=file('d:\\cpickle.data')

while True:
    content=f.readline()
    if len(content)==0:
        break;
    print(content)

f.seek(0) #重新定位到文件头,否则报错
shoplist2=P.load(f)
print(shoplist2)

输出:

(lp1

S'apple'

p2

aS'banana'

p3

aS'pear'

p4

a.
['apple', 'banana', 'pear']

 这个华丽丽的功能名字叫做:pickle ,建议用cPickle,速度是pickle的100倍。可以保存任意Python对象。
