import cPickle as p
#import pickle as p

AddressListfile = ‘AddressList.data‘ # the name of the file where we store the information

AddressList = {‘Xiaopeng Yang‘: (18000001219, ‘[email protected]‘)}

# Write to the file
f = file(AddressListfile, ‘w‘)
c = p.dump(AddressList, f) #dump the object to a file
f.close()

del AddressList # remove the AddressList

#Read back from the storage
d = file(AddressListfile)
shoredlist = p.load(d)
print shoredlist

Output

================= RESTART: /Users/zhouxin/Desktop/cPickle.py =================
{‘Xiaopeng Yang‘: (18000001219L, ‘[email protected]‘)}
>>>

 It also creates AddressList.data. 

About .data document: 

data是数据保存的备份类文件。里面存放的是加密后的数据文件，如模型、贴图、源程序代码等。data文件打开的方式是不确定的，如果是：
　　1、数据文件， 可以用txt或word直接打开
　　2、vcd格式的影音文件，可以用meidaplayer打开！

About pickle : 

you can store any Python object in a file and then get it back later intact. This is called storing the object persistently. 

Use the cPickle module to store the objects persistently on your hard disk.
