Python Special Syntax 8: 序列化与反序列化-->华丽丽的叫 pickle(泡菜?!)

直接上代码吧

#-*-coding:utf-8import  osif os.path.exists(d:\\cpickle.data):    os.remove(d:\\cpickle.data)import cPickle as Pshoplist=[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。
