iter_nest_dict(d: dict, iter_arrays: bool = False) → Iterable[tuple]

Iterate over a nested dictionary, yielding the key and value.

Parameters:

• d (dict) – The dictionary to iterate over.

• iter_arrays (bool)

Yields:

tuple – The key and value of the dictionary.

Return type:

Iterable[tuple]

Examples

>>> d = {'a': {'b': 1, 'c': 2}, 'd': {'e': 3, 'f': 4}}
>>> for k, v in iter_nest_dict(d):
...     print(k, v)
('a', 'b') 1
('a', 'c') 2
('d', 'e') 3
('d', 'f') 4
>>> d = {'a': {'b': np.array([1, 2]), 'c': 2}, 'd': {'e': 3, 'f': 4}}
>>> for k, v in iter_nest_dict(d, iter_arrays=False):
...     print(k, v)
('a', 'b') [1 2]
('a', 'c') 2
('d', 'e') 3
('d', 'f') 4
>>> for k, v in iter_nest_dict(d, iter_arrays=True):
...     print(k, v)
('a', 'b', 0) 1
('a', 'b', 1) 2
('a', 'c') 2
('d', 'e') 3
('d', 'f') 4
