Python Shelve模块

一、定义

也是序列化数据的模块，唯一区别为只有一个open函数，返回类似字典的对象，可读可写;key必须为字符串，而值可以是python所支持的数据类型

二、实例

1 import shelve
2 
3 f=shelve.open(r'sheve.txt')
4 # f['stu1_info']={'name':'egon','age':18,'hobby':['piao','smoking','drinking']}
5 # f['stu2_info']={'name':'gangdan','age':53}
6 # f['school_info']={'website':'http://www.pypy.org','city':'beijing'}
7 
8 print(f['stu1_info']['hobby'])
9 f.close()
