Recursively access dict via attributes as well as index access?

Question

I\'d like to be able to do something like this:

from dotDict import dotdictify

life = {\'bigBang\':
           {\'stars\':
               {\'planets\': []}

class Dotsdict(dict):
    def __init__(self, args, **kwargs):
        super(Dotsdict, self).__init__(args, **kwargs)
        for obj in [args, kwargs]:
            for k, v in obj.items():
                if isinstance(v, dict):
                    v = Dotsdict(v)
                self.__setitem__(k, v)

    def __setitem__(self, key, val):
        super(Dotsdict, self).__setitem__(key, val)
        # self.__dict__[key] = val

    def __delitem__(self, key):
        super(Dotsdict, self).__delitem__(key)
        # del self.__dict__[key]

    def __getitem__(self, key):
        return super(Dotsdict, self).__getitem__(key)

    def __missing__(self, key):
        dots = Dotsdict()
        self.__setitem__(key, dots)
        return dots

    __setattr__, __delattr__, __getattr__ = __setitem__, __delitem__, __getitem__

# ===================================================================


d = {'k': 'v', 'x': {'y': 'z', 'p': 'q', }, }
print(type(d))
print(d)

dd = Dotsdict(d, i='j')
print(type(dd))
print(dd)

print('========================================')

dd.a = 'b'
dd.x.m = 'n'
print(dd.x.y)

del dd.x['p']
print(dd)
print(len(dd))
