Python shelve

一、shelve模块时一个简单的k,v将内存数据通过文件持久化的模块，可以持久化任何pickle可支持的python数据的格式.

import shelve

d = shelve.open('shelve_test')#打开一个文件

class Test(object):
    def __init__(self,n):
        self.n = n

t = Test(123)
t2 = Test(12344)

name = ["wohaoshuai1","wohaoshuai2","wohaoshuai3"]

d["test"] = name
d["t1"] = t
d["t2"] = t2

d.close()

#解析
#a = shelve.open("shelve_test")
#a.get("test")
#b1 = a.get("t1")
#b2 = a.get("t2")
#print(b1.n)
#print(b2.n)
