        "description": "# Attr-Dict  \n\nYet another Attribute Dict implementation !  \n\nThis package provides a dictionary with attribute access to keys. It is especially convenient when working with deeply nested data. (Original idea from https://github.com/otsaloma/attd)\n\n\n**Different implementations** based on `OrderedDict`:  \n\n- **Strict**: **`AttrDict`**  \n    Work as a dictionary with class attribute syntax. Some keys cannot be translated to attributes (like int), in this case revert to usual dict syntax (ie: dict[key]).  \n\n- **Lazy**: **`LazyAttrDict`**  \n    Based on AttrDict but return None on missing keys, and mask values (list of keys on repr()).\n\n- **Restricted**: **`RestrictedAttrDict`**  \n    Lazy Attribute dictionary enforcing value change from dictionary syntax only (setitem & delitem), and masking values (return list of keys on repr()).  \n\n    Will raise AttributeError on Attribute change (setattr or delattr) to mimic @property attribute. \n\n\n#### Basic usage:\n```python\n# Some dict\n>>> conf_A = {'a': 1, 'b': 2, 'c': 3}\n>>> conf_B = {'a': 11, 'b': 12, 'c': {'c1': 13, 'c2': 23}}\n\n# import library\n>>> from attr_dict import AttrDict, LazyAttrDict, RestrictedAttrDict\n\n\n## Create a Lazy Attribute Dict\n>>> lad = LazyAttrDict()\n\n# Add some data (using different syntax)\n>>> lad.A = conf_A\n>>> lad['B']= conf_B\n\n# or\n>>> lad.update(dict(A=conf_A, B=conf_B))\n\n# Access data\n>>> lad\n{'A': {'a': 1, 'b': 2, 'c': 3}, 'B': {'a': 11, 'b': 12, 'c': {'c1': 13, 'c2': 23}}}\n>>> lad.A\n{'a': 1, 'b': 2, 'c': 3}\n>>> lad.A.c\n3\n>>> lad['A']['c']\n3\n>>> 'c' in lad.A\nTrue\n```\n\n\n#### Other features:\n```python\n# Export to JSON\n>>> json_data = lad.to_json()\n>>> print(json_data)\n{\n  \"A\": {\n    \"a\": 1,\n    \"b\": 2,\n    \"c\": 3\n  },\n  \"B\": {\n    \"a\": 11,\n    \"b\": 12,\n    \"c\": {\n      \"c1\": 13,\n      \"c2\": 23\n    }\n  }\n}\n\n## Import JSON to a new Attribute Dict\n>>> new_ad = AttrDict().from_json(json_data)\n>>> print(new_ad)\nAttrDict([('A', AttrDict([('a', 1), ('b', 2), ('c', 3)])), \\\n('B', AttrDict([('a', 11), ('b', 12), ('c', AttrDict([('c1', 13), ('c2', 23)]))]))])\n\n\n## Use Restricted Attribute Dict\n>>> rad = RestrictedAttrDict()\n\n# Add data using dict syntax (setitem)\n>>> rad['A'] = {}\n>>> rad['A']['a'] = 1\n>>> for k,v in conf_A.items():\n...     rad['A'][k] = v\n...\n\n# Data access to values is restricted\n>>> rad\n['A']\n>>> rad.A\n['a', 'b', 'c']\n>>> rad.A.b\n2\n>>> dict(rad.A)\n{'a': 1, 'b': 2, 'c': 3}\n\n\n# Attributes are protected\n>>> rad.A = conf_A                              # doctest: +ELLIPSIS\nTraceback (most recent call last):\n...\nAttributeError: can't set attribute\n\n>>> rad.A.b = 0                                 # doctest: +ELLIPSIS\nTraceback (most recent call last):\n...\nAttributeError: can't set attribute\n>>> del rad.A.b                                 # doctest: +ELLIPSIS\nTraceback (most recent call last):\n...\nAttributeError: can't delete attribute\n\n# Use dict syntax to change or delete\n>>> rad.A['b'] = 0\n>>> rad.A.pop('b')\n0\n\n# Missing key return None\n>>> print(rad.A.b)\nNone\n>>> 'b' in rad.A\nFalse\n```  \n\n\nRelative interfaces named '**indexes**' are also available to manage any king of objects with these attribute dictionaries:  \n**`AttrIndex`**, **`LazyIndex`**, **`RestrictedIndex`**  \n(current implementation only works on 2 levels)  \n\n#### Index usage:\n```python\n# Import & init\n>>> from attr_dict import LazyIndex\n>>> x = LazyIndex()\n\n# set keys & args\n>>> x.set_arg('A', a=1, b=2, c=3)\n>>> x.set_key('B')\n\n>>> x.index\n{'A': {'a': 1, 'b': 2, 'c': 3}, 'B': {}}\n\n# get, del & check\n>>> x.get_key('A')\n{'a': 1, 'b': 2, 'c': 3}\n>>> x.get_arg('A', 'b')\n2\n\n>>> x.del_arg('A', 'c')\n>>> x.get_key('A')\n{'a': 1, 'b': 2}\n\n>>> x.check_arg('A', 'b', 2)\nTrue\n```\n\n\n",
