本文介绍了将类保存到二进制文件中 - Python的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着跟版网的小编来一起学习吧！
问题描述
我知道可以使用以下方法将类保存到 c++ 中的二进制文件中:
I'm aware that saving a class into a binary file in c++ is possible using:
file.write(Class_variable, size_of_class, amount_of_saves, file_where_to_save)
或类似的东西，我想在 python 中使用它，以便更轻松地写入和读取大量数据.
or something similar, and I wanted to use that in python in order to make it easier to write and read lots of data.
我试过这样做:
def Save_Game(player, room):
address = 'Saves/player'
file = open(address, 'wb')
file.write(player)
address = 'Saves/room'
file = open(address, 'wb')
file.write(room)
房间和玩家是class_objects.但它说:
Room and player being class_objects. But it says:
TypeError: must be convertible to a buffer, not PlayerMarty
我能做什么?
推荐答案
pickle 是你需要的.pickle 模块实现了一种基本但强大的算法，用于序列化和反序列化 Python 对象结构.这是一个例子
pickle is what you need. The pickle module implements a fundamental, but powerful algorithm for serializing and de-serializing a Python object structure. This is an example
import pickle
class MyClass:
def __init__(self,name):
self.name = name
def display(self):
print(self.name)
my = MyClass("someone")
pickle.dump(my, open("myobject", "wb"))
me = pickle.load(open("myobject", "rb"))
me.display()
