Return structure of a dictionary object (without all the values):

import typing


def return_dict_structure(obj):
    """Return the structure of a possibly nested dictionary object."""
    new_obj = {}
    if isinstance(obj, typing.List) or isinstance(obj, typing.Tuple):
        if obj:
            return [return_dict_structure(obj[0]), '...']
        else:
            return []
    elif isinstance(obj, typing.Dict):
        for k, v in obj.items():
            new_obj[k] = return_dict_structure(v)
    else:
        return type(obj)
    return new_obj
