Python object and dictionary convertion

When programing in Python, sometimes you want to convert an object to dictionary and vise versal. In this article, I share my expericences to do that.

Convert from class to dictionary

When you want to convert a class to dictionary just define class override from object (this is important) and then call method __dict__:

>>> class Person(object):
        def __init__(self, age, name):
            self.age = age
   = name
>>> a = Person('kiennt', 24)
>>> a.__dict__
{ 'name' : 'kiennt', 'age' : 24 }

Convert from dictionary to class

In contrast, if you want to convert a dictionary to object, use this method. I did not invent this method, it is borrowed from

>>> class Struct(object):
        def __init__(self, **entries):
>>> d = { 'name' : 'kiennt', 'age' : 24 }
>>> a = Struct(**d)
>>> a.age

I change above methods like bellow to get recusive convertion dictionary:

class Struct(object):
    def __init__(self, adict):
        """Convert a dictionary to a class

        @param :adict Dictionary
        for k, v in adict.items():
        if isinstance(v, dict):
            self.__dict__[k] = Struct(v)

def get_object(adict):
    """Convert a dictionary to a class

    @param :adict Dictionary
    @return :class:Struct
    return Struct(adict)

That ’s it. Happy working with python!
