Save a class into a binary file - Python

Question

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)


        

Answer 1

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()

Answer 2

You can get at the bytes of Python objects to save & restore them like that, but it's not easy to do directly. However, the standard pickle module simplifies the process enormously.
