ncw
Nested collections wrapper
Classes to access and/or modify data in nested collections (dict or list instances)
of str, int, float, bool, or None, through a Mapping or
MutableMapping interface using direct addressing.
Usage
Use the FrozenStructure class to access data in nested collections by either
a string comprised of the segments of the keys or indexes in the "path" addressing the
substructure or value, joined together by a separator character
(usually an ASCII dot: .), or a tuple of these path segments.
>>> serialized = '{"herbs": {"common": ["basil", "oregano", "parsley", "thyme"], "disputed": ["anise", \
"coriander"]}}'
>>>
>>> import json
>>> original_data = json.loads(serialized)
>>>
>>> from ncw import FrozenStructure
>>> readonly = FrozenStructure.from_native(original_data)
>>>
>>> readonly["herbs"]
{'common': ['basil', 'oregano', 'parsley', 'thyme'], 'disputed': ['anise', 'coriander']}
>>> readonly["herbs.common"]
['basil', 'oregano', 'parsley', 'thyme']
>>> readonly["herbs", "common"]
['basil', 'oregano', 'parsley', 'thyme']
>>> readonly["herbs.common.1"]
'oregano'
>>> readonly["herbs", "common", 1]
'oregano'
The MutableStructure class additionally allows changes to the stored data, see the documentation for more details.
