Had the same issue.
This works for me:

Hey!

Unfortunately, it's (afaik) not possible to get addicts functionality without creating an empty dictionary on lookup. Essentially, when you do my_dict.a.b = 2, Python first tries to figure out what my_dict.a.b is. If my_dict.a does not exist when __getattr__ is called on my_dict, Python will raise an exception. Hence, as a workaround, and tbh this is the whole idea that makes addict work, we return a empty dictionary, so that when the __setattr__ is called on my_dict.a we're able to do set the item in my_dict.

If I'm not misunderstanding the question you could always call .to_dict() in order to transform it into a regular python dict, and disallow further __setattr__.

Cheers,

Mats

If you just use .to_dict() you will lose the dot-access to dict items too!

That's true @Ohjeah.

Hence the LockedDict (see the gist). It serves as a read only version of addict.Dict. Works well for me if I want an exception rather a None value return on a failed item lookup.
