面试题：Python类序列化与反序列化之中等题

Question

在Python中，使用pickle模块对一个自定义类进行序列化和反序列化。假设自定义类有两个属性，分别为字符串类型的name和整数类型的age，要求在反序列化后能正确还原对象的属性值。请写出完整代码。

Answer 1

import pickle


class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age


# 序列化
person = Person("张三", 25)
with open('person.pkl', 'wb') as f:
    pickle.dump(person, f)

# 反序列化
with open('person.pkl', 'rb') as f:
    deserialized_person = pickle.load(f)

print(f"Name: {deserialized_person.name}, Age: {deserialized_person.age}")
