pickle序列化模块

pickle序列化模块

优势：能够序列化python中所有的类型
缺陷：只能够再python中使用，无法跨语言传输

需求：产生一个对象并保存到文件中，取出来还是一个对象

class C1:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def func1(self):
        print('from func1')

    def func2(self):
        print('from func2')


obj = C1('jason', 18)
import pickle

with open(r'a.txt', 'wb') as f:
    pickle.dump(obj, f)
with open(r'a.txt', 'rb') as f:
    obj = pickle.load(f)

print(obj.func2())
