代码：

#!/usr/bin/python
# Filename: pickling.py

import cPickle as p
#import pickle as p

shoplistfile = 'shoplist.data'
# the name of the file where we will store the object

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

# Write to the file
f = file(shoplistfile, 'w')
p.dump(shoplist, f) # dump the object to a file
f.close()

del shoplist # remove the shoplist

# Read back from the storage
f = file(shoplistfile)
storedlist = p.load(f)
print storedlist

程序运行结果：

['apple', 'mango', 'carrot']

shoplist.data的内容：

(lp1
S'apple'
p2
aS'mango'
p3
aS'carrot'
p4
a.

dump()出来的文件还是要用load()来读比较好。
