# 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：
