orderedattrdict 1.0.1

OrderedDict with attribute-style access

An ordered dictionary with attribute-style access.

Usage

AttrDict behaves exactly like collections.OrderedDict, but also allows keys to be accessed as attributes.

>>> from orderedattrdict import AttrDict
>>> conf = AttrDict()
>>> conf['z'] = 1
>>> assert conf.z == 1
>>> conf.y = 2
>>> assert conf['y'] == 2
>>> conf.x = 3
>>> assert conf.keys() == ['z', 'y', 'x']

NOTE: If the key clashes with an AttrDict attribute, the key is not used. This also applies if the key starts with __ (two underscores). For example:

>>> a = AttrDict(keys=1)
>>> a.keys
<bound method AttrDict.keys of AttrDict([('keys', 1)])>
>>> a['keys']
1

JSON files can be parsed using AttrDict as follows:

>>> import json
>>> data = json.load(open('file.json'), object_pairs_hook=AttrDict)

YAML files can be parsed using AttrDict as follows:

>>> import yaml
>>> from orderedattrdict import AttrDictYAMLLoader
>>> data = yaml.load(open('file.yaml'), Loader=AttrDictYAMLLoader)

YAML files can be saved from AttrDict structures as follows:

>>> from orderedattrdict import AttrDictYAMLDumper
>>> yaml.dump(data, Dumper=AttrDictYAMLDumper)

Installation

pip install orderedattdict

This is a pure-Python package is build for Python 2.7+ and Python 3.0+.
