.. py:class:: pydu.dict.AttrDict(seq=None, **kwargs)
|
|
|
|
A AttrDict object is like a dictionary except ``obj.foo`` can be used
|
|
in addition to ``obj['foo']``.
|
|
|
|
>>> from pydu.dict import AttrDict
|
|
>>> o = AttrDict(a=1)
|
|
o.a
|
|
1
|
|
>>> o['a']
|
|
1
|
|
>>> o.a = 2
|
|
>>> o['a']
|
|
2
|
|
>>> del o.a
|
|
>>> o.a
|
|
Traceback (most recent call last):

... AttributeError: 'a'

.. py:class:: pydu.dict.CaseInsensitiveDict(data=None, **kwargs)
|
|
|
|
A case-insensitive ``dict``-like object.
|
|
Implements all methods and operations of ``collections.MutableMapping``
|
|
as well as dict's ``copy``. Also provides ``lower_items``.
|
|
All keys are expected to be strings. The structure remembers the
|
|
case of the last key to be set, and ``iter(instance)``, ``keys()``,
|
|
``items()``, ``iterkeys()``, and ``iteritems()`` will contain
|
|
case-sensitive keys.
|
|
|
|
>>> from pydu.dict import CaseInsensitiveDict
|
|
>>> cid = CaseInsensitiveDict()
|
|
>>> cid['Accept'] = 'application/json'
|
|
>>> cid['aCCEPT'] == 'application/json'
|
|
True
|
|
>>> list(cid) == ['Accept']
|
|
True
|
|
|
|
|
|
.. py:class:: pydu.dict.LookupDict(name=None)
|
|
|
|
Dictionary lookup object.
|
|
|
|
>>> from pydu.dict import LookupDict
|
|
>>> d = LookupDict()
|
|
>>> d['key']
|
|
None
|
|
>>> d['key'] = 1
|
|
>>> d['key']
|
|
1
|
|
|

|
|
.. py:function:: pydu.dict.attrify(obj)
|
|
|
|
Attrify obj into ``AttriDict`` or ``list of AttriDict`` if the obj is list.
|
|
|
|
>>> from pydu.dict import attrify
|
|
>>> attrd = attrify({
|
|
'a': [1, 2, {'b': 'b'}],
|
|
'c': 'c',
|
|
})
|
|
>>> attrd
|
|
<AttrDict {'a': [1, 2, <AttrDict {'b': 'b'}>], 'c': 'c'}>
|
|
>>> attrd.a
|
|
1
|
|
>>> attrd.a[2].b
|
|
b
|
|
>>> attrd.c
|
|
c
