# 序列化对象p1
import pickle # 内置库
class People:
def __init__(self, name, age):
self.name = name
self.age = age
def sayhi(self):
print("Hi, my name is {}, and I'm {}".format(self.name, self.age))
p1 = People(name="Jack", age=30)
p1.sayhi() # Hi, my name is Jack, and I'm 30
f = open('p1', 'wb') # 以二进制的方式
pickle.dump(p1, f) # 参数为python的对象和文件句柄
f.close()
这样写入python对象后,在程序目录下产生一个p1文件
下面我们来加载这个p1文件,从而使用p1这个对象对应的类中的属性
import pickle
class People:
def __init__(self, name, age):
self.name = name
self.age = age
def sayhi(self):
print("Hi, my name is {}, and I'm {}".format(self.name, self.age))
# 测试序列化对象的加载
f = open('p1', 'rb') # 用二进制的方式读
p2 = pickle.load(f) # 可以把p1文件中python对象加载到内存中,再把这个对象赋给p2
print(p2, p2.name, p2.age) # <__main__.people object at> Jack 30
p2.sayhi() # Hi, my name is Jack, and I'm 30
)
