python - Subclassing dict and nested dicts in it -

i have nested dictionary want convert next subclass did:

class subdict(dict): def __getattr__(self, attr): if attr in self.keys(): homecoming self.get(attr)

and if do, works great base of operations dict :

my_nested_dict = subdict(my_nested_dict)

but need nested ones converted subdict too. how accomplish that?

thanks!

you need recurse on nested dictionaries , convert recursively:

class subdict(dict): def __init__(self, *args, **kw): super(subdict, self).__init__(*args, **kw) key, value in self.iteritems(): if isinstance(value, dict): self[key] = subdict(value)

have looked collections.defaultdict @ all? can create tree scratch quite easily:

import defaultdict def tree(): homecoming defaultdict(tree)

python dictionary python-2.7 override subclass
