Attribute dictionary implementation that allow get access to their elements by keys (as native dict) and attributes.

Attribute dictionary implementation that allow get access to their elements by keys (as native dict) and attributes.

Installation:

pip install attrd

Usage:

    from attrd import AttrDict

    a = AttrDict(key1=123)

    # Set value by attribute
    a.key2 = 123

    # Set value by key
    a['key3'] = 123

    # Set and delete value by attribute
    a.key4 = 123
    del a.key4

    # Set and delete value by key
    a['key5'] = 123
    del a['key5']

    print(a) # -> {'key1': 123, 'key2': 123, 'key3': 123}

Convert existed dict to AttrDict:

    print(AttrDict({'key1': 123, 'key2': 123})) # -> {'key1': 123, 'key2': 123}

    print(AttrDict(**{'key1': 123, 'key2': 123})) # -> {'key1': 123, 'key2': 123}

Nested level:

    d = {
        'key1': {
            'sub_key1': 123,
            'sub_key2': {
                'deep_key': 'abc'
            }
        }
    }

    d = AttrDict(d)
    d.key1.sub_key3 = 123

    print(d.key1) # -> {'sub_key1': 123, 'sub_key2': {'deep_key': 'abc'}, 'sub_key3': 123}
    print(d.key1.sub_key1) # -> 123
    print(d.key1.sub_key2.deep_key) # -> abc

    del d.key1.sub_key2
    print(d) # -> {'key1': {'sub_key1': 123, 'sub_key3': 123}}

Nested values with kwargs:

    d = AttrDict(key1={'sub_key1': 123, 'sub_key2': 123})

    print(d) # -> {'key1': {'sub_key1': 123, 'sub_key2': 123}}
    print(d.key1.sub_key1) # -> 123

    del d.key1.sub_key2
    print(d) # -> {'key1': {'sub_key1': 123}}

Dicts in lists:

    d = AttrDict({
        'key1': [
            {'sub_key1': 123, 'sub_key2': 456},
            {'sub_key1': 123, 'sub_key2': 456},
        ]
    })

    del d.key1[0].sub_key2, d.key1[1].sub_key1
    print(d) # -> {'key1': [{'sub_key1': 123}, {'sub_key2': 456}]}
    print(d.key1[0].sub_key1) # -> 123

Iterate items:

    g = AttrDict(a=1, b=2, c=3, items=[10, 11, 12])

    print(g.items) # -> <built-in method items of AttrDict>
    print(g.get('items')) # -> [10, 11, 12]

    for k, v in g.items():
        print(k, v)

    # a 1
    # b 2
    # c 3
