import cPickle as p
#import pickle as p

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

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

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

del shoplist #remove the shoplist

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

先创建shoplist.data，然后向里面追加数据，最后读取

注意方法：

p.dump(shoplist,f)

p.load(f)
