nip.utils.data.nested_dict_keys

nip.utils.data.nested_dict_keys(data: dict) → list[tuple[str, ...]]

Get the keys of a nested dict as a list of tuples of strings.

A nested dict is a dict that may contain other dicts as values. This function recursively traverses the dict to get all the keys, where each key is a tuple of strings.

Parameters:

data (dict) – The nested dict to get the keys of.

Returns:

keys (list) – The keys of the nested dict.

Examples

>>> data = {"a": {"b": 1, "c": 2}, "d": 3}
>>> get_nested_dict_keys(data)
[("a", "b"), ("a", "c"), ("d",)]
