本文介绍了一个使用Python的pickle模块实现对象持久化的简单示例。通过将Person类实例保存到文件并从中读取，展示了如何序列化和反序列化对象。

代码

# file's name : obj_w_r.py

# import cPickle as pk
import pickle as pk

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age
    def sayhi(self):
        print "Hello everyone, my name is", self.name, ", I'm", self.age, "years old"

p = Person("nami", 24)

filename = "c:/nami.data"

# save person to nami.data
f = file(filename, "w")
pk.dump(p, f)
f.close()

# read person from nami.data
f = file(filename)
p = pk.load(f)

# call person's sayhi method
p.sayhi()

输出结果：
Hello everyone, my name is nami , I'm 24 years old
